Subject: [PATCH] gitk: Don't show local changes when we there is no work tree
X-Git-Url: http://privyetmir.co.uk/gitweb?a=commitdiff_plain;h=cb8329aa9a6cc2e009d552b1180ce107cec4eb9d;p=gitk

[PATCH] gitk: Don't show local changes when we there is no work tree

Launching gitk on a bare repository or a .git directory
would previously show the work tree as having removed all
files.  We now inhibit showing local changes when gitk
is not launched from within a work tree.
