Wrong gitignore precedence?

Hello All,

I read the document of gitignore (http://git-scm.com/docs/gitignore), and learned that $GIT_DIR/info/exclude has higher precedence than the file specified by core.excludesfile.

But I noticed that patterns in core.excludesfile override patterns in $GIT_DIR/info/exclude.

I tested as below:

   1. Make a new git repository for test, and move into the repository.
      $ git init testrepo
      $ cd testrepo
   2. Change core.excludesfile configuration.
      $ touch ../core_excludesfile
      $ git config core.excludesfile `realpath ../core_excludesfile`
   3. Create test~. In each step I check if the file is ignored or not.
      $ touch test~
   4. See git status. In this case I expect that test~ should not be ignored.
      $ git status --ignored
   5. Change settings in .git/info/exclude.
      $ echo '*~' > .git/info/exclude
   6. See git status. In this case I expect that test~ should be ignored.
      $ git status --ignored
   7. Change settings in .git/info/exclude and core.excludesfile.
      $ echo '*~' > ../core_excludesfile
      $ echo '!*~' > .git/info/exclude
   8. See git status. In this case I expect that test~ should not be ignored.
      $ git status --ignored
   9. Change settings in .git/info/exclude and core.excludesfile
      $ echo '!*~' > ../core_excludesfile
      $ echo '*~' > .git/info/exclude
  10. See git status. In this case I expect that test~ should be ignored.
      $ git status --ignored

Steps 4. and 6. worked as I expected, but 8. and 10. didn't.

I read the source code of Git, and found out the point that seems to cause the problem.

In dir.c, setup_standard_excludes() adds patterns in .git/info/exclude to the excludes list first, and patterns in core.excludesfile are added next.

In last_exclude_matching_from_list(), pattern is searched from the end of the list, and the first matching pattern is used. Therefore the patterns in core.excludesfile are used in precedence to .git/info/exclude.

To meet the precedence described in the document of gitignore, I guess setup_standard_excludes() should be fixed so that patterns in core.excludesfile are added to the list before those in .git/info/ecdlude are added.

Thanks
