.gitignore regex for emacs temporary files

Question

I'm trying to .gitignore emacs temporary/autosave files. I'm using...

\.\#.* 

in my .gitignore.

But git add -A run in a subfolder is still giving me:

#       new file:   .#make_collections.py #       new file:   .#norm_collections.py #       new file:   make_collections.py #       new file:   norm_collections.py 

even though

\.\#.* 

is clearly getting the right file names and not the wrong ones when I test it with a regex tester.
