Exclude .svn folders within git
Solution 1:
I think you want to use a .gitignore file in your top-level directory. This will work if you put ".svn/entries" on a line in that file. You might just put ".svn" instead of ".svn/entries" as well.
EDIT: See comments. If they files are already being tracked by git, they'll always show up in git status
.
Solution 2:
This thread has the correct answer:
Git - Ignore certain files contained in specific folders
What you really need is:
.svn*
