This check used to be in src/elinks.h. Move it to configure.in so
that (1) the result can be logged and (2) ELinks won't even link with
TRE if wchar_t prevents its use.
Also, rename HAVE_TRE_REGEX_H to CONFIG_TRE, to reflect that it is not
always defined if the header exists.
The previous version could display its progress like this:
checking for TRE... checking for TRE in pkg-config... yes
checking for TRE header and library... yes
no
Omit the outer "checking for TRE..." and "no" (which was untrue
anyway), unless --without-tre causes the inner checks to be skipped.

elinks-lite in Debian does not depend on any libraries (except
gnutls). Including this option will allow elinks-lite to be built
without libtre dependency.

src/session/session.c: Kept the elinks-0.13 version.
Bug 1077 did not occur in elinks-0.13 because
setup_session here calls render_document_frames
directly and that sets ses->doc_view->vs.
At the end of the destroy_vs there two assignments vs->doc_view->vs = NULL and
vs->doc_view = NULL. In the setup_session the copy_vs left the vs "unbound"
with any variable. At least one of these two is wrong.
The AsciiDoc 7.1.2 configuration files included in the ELinks
source tree apparently aren't compatible with AsciiDoc 8.4.4:
[ASCIIDOC] doc/elinks.1.xml
FAILED: [listdef-bulleted] missing section: [listtags-None]
make[1]: *** [elinks.1.xml] Error 1
Fix this by including asciidoc.py from AsciiDoc 7.1.2 as well.
The build system now doesn't care at all whether the user has
installed some version of AsciiDoc or not.
Fix this error when configured with --enable-debug --disable-utf-8:

When setting up default values for terminal options, use named
constants like TERM_VT100 or COLOR_MODE_16, rather than plain integers
like 1. This is just to make the source code easier to read and
perhaps more resistant to future bugs. The binary should not change.
If globhist_simple_search ran out of memory in stracpy(search_url), it
could leave gh_last_searched_title pointing to freed memory and cause
a crash in the next call. Fix by not freeing gh_last_searched_title.
It is then possible to have gh_last_searched_title and
gh_last_searched_url pointing to strings from different searches;
but that was already possible if stracpy(search_title) failed.
Because this bug occurs only in out-of-memory situations and I don't
think ELinks in general has been properly tested in those, the fix is
perhaps not worth mentioning in NEWS and backporting to elinks-0.11.
If the parent parameter of get_dom_node_list_index referred to a node
that did not have children, then get_dom_node_list called by it could
return the address of a null pointer, and get_dom_node_list_index would
then pass that null pointer to get_dom_node_list_pos, which would crash.
That would be the same kind of crash as the one in get_dom_node_child.
It never happened in practice though: because all calls are in the form
get_dom_node_list_index(node->parent, node), the list must contain at
least the given node, and the pointer cannot be null. The documentation
of get_dom_node_list_index allows arbitrary nodes as arguments however,
so it's best to add a check.
struct dom_node contains a union that contains various structs that
have members of type struct dom_node * in them.
get_dom_node_list_by_type returns the address (struct dom_node **) of
one of those members, or NULL. However the member itself can also be
NULL if no nodes have been added to the list and the list has thus not
yet been allocated. (add_to_dom_node_list lazily allocates the lists.)
get_dom_node_child did not expect a null pointer there and crashed, as
shown in bug 1071. Fix by adding a check so that it treats a NULL list
as an empty list.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
Documentation strings of most options used to contain a "\n" at the
end of each source line. When the option manager displayed these
strings, it treated each "\n" as a hard newline. On 80x24 terminals
however, the option description window has only 60 columes available
for the text (with the default setup.h), and the hard newlines were
further apart, so the option manager wrapped the text a second time,
resulting in rather ugly output where long lones are interleaved with
short ones. This could also cause the text to take up too much
vertical space and not fit in the window.
Replace most of those hard newlines with spaces so that the option
manager (or perhaps BFU) will take care of the wrapping. At the same
time, rewrap the strings in source code so that the source lines are
at most 79 columns wide.
In some options though, there is a list of possible values and their
meanings. In those lists, if the description of one value does not
fit in one line, then continuation lines should be indented. The
option manager and BFU are not currently able to do that. So, keep
the hard newlines in those lists, but rewrap them to 60 columns so
that they are less likely to require further wrapping at runtime.
test_search() was supposed to compare bookmark titles with
strcasestr(), but in commit 311d95358d
"bug 153, 1066: Convert bookmarks to/from UTF-8 when searching."
on 2009-02-08, I inadvertently changed that to strcasecmp(), even
while adding a comment about why strcasestr() is needed. strcasestr()
returns non-NULL if the strings match, and strcasecmp() returns
nonzero if they differ, so the search didn't work at all.
This reverts commit b94657869b.
I don't know where I got the idea that JS_SetErrorReporter affects the
entire JSRuntime, rather than only the provided JSContext. The people
on #jsapi say it has never worked that way.
