[Bug 1336230] [NEW] core.worktree misinterpreted by Git GUI

[Martin Pecka]

Public bug reported:

I have a "super-repository" tradr-simulation which contains several
subfolders. I wanted to share some of the subfolders through another Git
repository, so I created an "external subrepository" - the .git resides
above tradr-simulation in the filesystem, and in its config I've set
core.worktree to point to tradr-simulation (particularly worktree =
../../../tradr-ws/src/tradr-simulation ).

Now here's what's shown in CLI (CWD is the "external subrepo"):

--------------

D:\Programování\tradr-git\non-tradr-share\robot-model>git log
fatal: bad default revision 'HEAD'

D:\Programování\tradr-git\non-tradr-share\robot-model>git status
On branch master

Initial commit

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        .gitignore
        README
        gazebo-test/
        nifti_robot_description/
        nifti_robot_gazebo/
        vrep_ugv_simulation/

nothing added to commit but untracked files present (use "git add" to
track)

 -------------

However, if I start Git GUI from the "external subrepo", it is somehow
misled to think I wanted it to show the "super-repository". In the
screenshot attached, you can see how Git GUI looks when called as:

D:\Programování\tradr-git\non-tradr-share\robot-model>git gui

The window title as well as the Unstaged changes correspond to those of
the "super-repo", even though I started Git GUI from the "external
subrepo" directory.

** Affects: git (Ubuntu)
     Importance: Undecided
         Status: New

** Attachment added: "Git GUI called from the "external subrepo" directory with wrong interpretation of core.worktree"
