git grep bug replacing - with :

[Rickard Andersson <rickard.a1992@gmail.com>]

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)
   Added 2 files to my repo with words in them
   text-file.txt
   text-file-file.txt

   I did a git grep for said words that exists in both, and used
argument `-l` to only
   show matching filename
   ```
   git grep -l ExtremelyInterestingWord
   ```

What did you expect to happen? (Expected behavior)
   I expected to get the following output
   ```
   text-file.txt
   text-file-file.txt
   ```

What happened instead? (Actual behavior)
   I get
   ```
   text:file.txt
   text:file-file.txt
   ```


What's different between what you expected and what actually happened?
   It seems that when using the argument `-l` the first `-` in a filename is
   replaced with a `:`. It also seems that it is just the first one as the
   second file keeps it's second occurence of `-`.
