Subject: [PATCH] gitk: Fix for tree view ending in nested directories
Message-ID: <20070704212643.GR4087@lavos.net>
URL: https://gitlist.dev/e/20070704212643.GR4087%40lavos.net

```
Unroll the prefix stack when assigning treeheights when leaving
proc treeview.  Previously, when the ls-tree output ended in
multiple nested directories (for instance in a repository with a
single file "foo/bar/baz"), $treeheight("foo/bar/") was assigned
twice, and $treeheight("foo/") was never assigned.  This led to
an error when expanding the "foo" directory in the gitk treeview.
