cgit.c: Do not restore unset environment variables

getenv() returns a NULL pointer if the specified variable name cannot be
found in the environment. However, some setenv() implementations crash
if a NULL pointer is passed as second argument. Only restore variables
that are not NULL.

See commit d96d2c98ebc4c2d3765f5b35c4142e0e828a421b for a related patch.

This whole time I thought OpenBSD xterm for some reason didn't support focus events. It turns out allowMouseOps: false disables them by default. Replace the disallowedMouseOps list with everything but. 2021-09-23Use NI_NUMERICSERVJune McEnroe 2021-09-23Make up build away from FreeBSDJune McEnroe 2021-09-23Add quickJune McEnroe 2021-09-23Add The HobbitJune McEnroe Surprisingly good for something written by a man like a hundred years ago! 2021-09-22Remove PSF fontsJune McEnroe They were fun to make but I never actually used them. 2021-09-22Remove Linux-specific utilitiesJune McEnroe I haven't used these in ages. 2021-09-22Call sandbox in CGI modeJune McEnroe Otherwise upload won't actually work. 2021-09-22Support HTTP PUT in upJune McEnroe For use by Palaver[1]. Unfortunately, at least in the current App Store version of Palaver, this doesn't work correctly with basic auth.

Almost all the remaining time is spent in deflate. 2021-09-21Rewrite pngo, add explicit optionsJune McEnroe Interesting to see how my code habits have changed. 2021-09-16Fix /* **/ comment matchingJune McEnroe 2021-09-15Remove typer, add downgrade to READMEJune McEnroe 2021-09-15Set bot mode on downgradeJune McEnroe 2021-09-15Enter capsicum in downgradeJune McEnroe 2021-09-15Factor out common parts of downgrade messagesJune McEnroe Also bump the message cap to 1024 because that is ostensibly useful for replying to older messages. 2021-09-14Add downgrade IRC botJune McEnroe 2021-09-14Sort by title if authors matchJune McEnroe There are probably better things to sort by but title definitely always exists. 2021-09-13Swap-remove tags as they're foundJune McEnroe This makes it even faster. From ~1s on a sqlite3.c amalgamation to ~0.85s. 2021-09-12Replace htagml regex with strncmpJune McEnroe Since ctags only ever produces regular expressions of the form /^re$/ or /^re/ with no other special characters, instead unescape the pattern and simply use strncmp. Running on a sqlite3.c amalgamation, the regex version takes ~37s while the strncmp version takes ~1s, producing identical output. Big win! 2021-09-11Also defer printing comment for lone close-parensJune McEnroe 2021-09-10Publish "git-comment"June McEnroe 2021-09-10Add git comment --pretty optionJune McEnroe 2021-09-08Defer printing comment if line is blank or closing braceJune McEnroe This fixes badly indented comments. 2021-09-08Up default min-repeat to 30 linesJune McEnroe 2021-09-08Handle dirty lines in git-commentJune McEnroe 2021-09-08Document and install git-commentJune McEnroe 2021-09-08Add repeat and all options to git-commentJune McEnroe 2021-09-08Add group threshold to git-commentJune McEnroe
