git grep doesn't follow symbolic link

Hi,

I've not found information about that in documentation, so I do a report.

When using git grep, symbolic links are not followed. Is it a wanted behavior ?

I've tested with a symbolic link:
 - 'ignored'
 - NOT staged for commit
 - to be commited
 - commited
Anytime -> no result when asking on symbolic link

Example: # git grep foo mySrc -> OK answer [...]

# ln -s mySrc test # git grep foo test -> KO: No answer

# git add test # git grep foo test -> KO: No answer

# git commit -m "DO NOT PUSH" test # git grep foo test -> KO: No answer
