* Fix a startup crash that's extremely easy to trigger on OpenBSD
(patch-draw_c).
* Various fixes from a forked Github version (there was no official
elvis release since 2004), clang warns about most of them.
* Remove some questionable/broken/dangerous features: backtick
support in filenames, WYSIWYG for nroff/tex files, and
HTTP/FTP support. Looking at the code, I'd feel better having
less features, here. Please complain if you really want them.
* Remove dead FTP mirrors from MASTER_SITES, and use an HTTP server
instead.
* Remove some previous patches of mine which only dealt with
whitespace in man pages: fixing that was just useless noise.
- add --docdir so that :help works
- add --verbose
- fix a bug in the ")" command that could cause a segfault
- fix a bug when lauching elvis in a directory containing a "tags" dir
- make file/syntax detection work for scripts using "env"
- add "return" to the list of shell script keywords
- fix a few things in the man pages (\-, typo, whitespace) since
we were already patching them.
