Subject: gui: Make $first a local variable of _get_subtree().
X-Git-Url: http://git.tuebingen.mpg.de/?p=gsu.git;a=commitdiff_plain;h=4e70cf69ed41bbf2cf1983cdae4ea3f6d2f1c684

gui: Make $first a local variable of _get_subtree().

Apparently this was missed when the function was introduced. The
variable is only referenced in _get_subtree().
