* 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.
