[PATCH] Fix the remote note the fetch-tool prints after storing a fetched reference

Otherwise ".git" is removed from every remote path which has it,
including "/some/path/somename.git".

Fixed truncation of "/.git/" (with a trailing slash).
The old code broke t5515, because it has left "../.git/"
unchanged, but should have removed ".git/".

Subject: [PATCH] Fix the remote note the fetch-tool prints after storing a fetched reference

Otherwise ".git" is removed from every remote name which has it:

  $ git fetch -v
    * refs/heads/origin: same as branch 'master' of /home/user/linux
      commit: 5ecd310
  $ ls /home/user/linux
  ls: /home/user/linux: No such file or directory
  $ ls /home/user/linux.git
  HEAD  objects  packed-refs  ...
