Subject: [PATCH] gitk: Fix for tree view ending in nested directories
X-Git-Url: http://privyetmir.co.uk/gitweb.cgi?a=commitdiff_plain;h=096e96b493bfc30687c87b303b93e75864942786;p=gitk

[PATCH] gitk: Fix for tree view ending in nested directories

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.
