Fix #13904, close #13908.
Previously many messages got clobbered. Now it should be better.
The solution is still relatively hacky, but I don't see how to improve
it without doing lots of work.
Fixes regression introduced by 16406e63b3.
Not replacing "egrep" with a negated character class on [^e] needs to be
put back into the replacement, because if we have something like:
foo="$(grep xxx)"
The replacement would be something like this:
foo="$/nix/store/.../bin/grep xxx)"
Which will lead to wrong behavior and in cases of for example
"xdg-screensaver", even directly to a syntax error:
xdg-screensaver: line 178: syntax error near unexpected token `('
xdg-screensaver: line 178: `command="/nix/store/.../bin/grep -E
"^Exec(\[[^]=]*])?=" "$file" |
/nix/store/.../bin/cut -d= -f 2- |
first_word`"'

Change xdg-utils fetchgit url to `http` alternative since it is
more proxy-friendly. The list of repository url alternatives
can be found at http://cgit.freedesktop.org/xdg/xdg-utils/
Fixes #6193.
Disabling docs generation might be another alternative
to the build-time dependency blowup.
That KDE patch no longer applies, but the code seems to take KDE5 into
account already. CC @ttuegel.
