Patch: git-add --exclude=pattern
git-ls-files has an argument "--exclude=<pattern>". I have
copied the relevant code snippets to do the same for git-add-files.
I want this facility so that I can disable processing of
.gitignore files for some shell scripts that I've cobbled together
to update git repositories from tar files of new versions of software
packages. Adding "!*" to .git/info/exclude does not achieve this,
because the .gitignore files have priority, and I can see arguments
why this should be so, so that .git/info/exclude can just encode
defaults and individual directories can have more specific rules.
In comparison, passing "--exclude='!*'" apparently does have priority
over the .gitignore files.
By the way, the particular situation where I had this problem
was in linux-2.6.19, which shoots itself in the foot a bit by including
.gitignore files that exclude source files like arch/*/kernel/vmlinux.ld.S,
include/asm-*/{alternative-asm,frame}.i and the .cvsignore files themselves.
However, fixing this linux kernel problem is not the point of this email.
I want a facility that can reliably add files from source trees even if
they have minor bugs like this in their .gitignore rules. Many thanks to ShadeHawk on the git IRC channel for pointing
out to me that the git-find-ls manual page actually describes the problem
and a fix for the case of vmlinux.ld.S in the linux kernel tree, and for
suggesting --exclude=pattern instead of --exclude-per-directory=filename.
