Writing patches for git-ignored files

[Khoo Wei Ming]

I followed the patching guidelines on

http://wiki.documentfoundation.org/Development/Patch_Handling_Guidelines

What is procedure for git-ignored files? E.g.

~/libo-git/moz$ git add
unxlngi6.pro/misc/build/mozilla/xpcom/glue/nsBaseHashtable.h
The following paths are ignored by one of your .gitignore files:
moz/unxlngi6.pro
Use -f if you really want to add them.
fatal: no files added

I'm assuming the '-f' option isn't the answer.

Cheers,
Wei Ming
