The GNU Hurd has a bug that can make select() report an exception in a
pipe even though none has actually occurred. The typical result is
that ELinks closes the pipe through which it internally passes all
input events, such as keypresses. It then no longer reacts to what
the user is trying to do.
Work around the Hurd bug by making set_handlers() check whether the
file descriptor refers to a pipe, and if so, pretend the caller did
not provide any handler for exceptions. This is a minimal change that
avoids slowing down the select() loop itself and does not require
careful analysis of the callers to statically find out which file
descriptors might refer to pipes. The extra stat() calls may slow
ELinks down somewhat, but anyway it'll work better than it did without
the patch, and if the Hurd bug is ever fixed, we can remove the
workaround at that time.

The following files also conflicted, but they had not been manually
edited in the elinks-0.12 branch after the previous merge, so I just
kept the 0.13.GIT versions:
doc/man/man1/elinks.1.in
doc/man/man5/elinks.conf.5
doc/man/man5/elinkskeys.5
po/fr.po
po/pl.po
This reverts commit c33d195ff4.
ELinks no longer needs to collect garbage in this situation
because it can now free cache entries even if the corresponding
SMJS objects remain.
Wrap on spaces when features are sent to console using -version,
and let Info dialog do the job in interactive mode.
Insert newlines and remove parenthesis in -version and Info box display.
Backported from master branch.
There were conflicts in src/document/css/ because 0.12.GIT switched
to LIST_OF(struct css_selector) and 0.13.GIT switched to struct
css_selector_set. Resolved by using LIST_OF(struct css_selector)
inside struct css_selector_set.
string_concat reads the args with va_arg(ap, const unsigned char *),
and the NULL macro may have the wrong type (e.g. int).
Many places pass string literals of type char * to string_concat.
This is in principle also a violation, but I'm ignoring it for now
because if it becomes a problem with some C implementation, then so
will the use of unsigned char * with printf "%s", which is so
widespread in ELinks that I'm not going to try fixing it now.
The configure script no longer recognizes "CONFIG_UTF_8=yes" lines
in custom features.conf files. They will have to be changed to
"CONFIG_UTF8=yes". This incompatibility was deemed acceptable
because no released version of ELinks supports CONFIG_UTF_8.
The --enable-utf-8 option was not renamed.
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
Mostly non-ANSI function declarations, using 0 as NULL and inline
function prototypes. Also removed unused S_HTTP_100 network state
enum type, which text message contained unknown escape sequence: '\?'.
