Hmm, in this case it might be easier to phrase the match positively:
git ls-files -- \*.c \*.h \*.l \*.y \*.cpp \*.cc \*.tcc |
sort |
cscope -R -b -i- -f"$PROJDIR"/cscope.out
So here’s another documentation bug: nowhere in the git-ls-files man page
does it explain that the filenames it takes are glob patterns.
(If you want to take patterns from a file, the shell makes this a little
trickier than I would like. At least
<.cscope-files xargs -d "\n" git ls-files --
works as expected.)

Right. The -X option is already used by some commands (e.g., git-gui) to
support .gitignore, so I do not think it can be used for this. I am not
sure whether adding an option that can be used would be worth the
complication, but if you have some idea of how this should work, you or I
could try sending a patch.
Thanks for the explanation.
Best wishes,
Jonathan
