Paul Mackerras 5a7f577dce gitk: Fix bug causing Tcl error when no commits are selected
Some of the stuff that commit 31c0eaa8cc
added to drawvisible isn't appropriate to do when we have no commits,
and this was causing a Tcl error if gitk was invoked in such a fashion
that no commits were selected.  This fixes it by bailing out of
drawvisible early if there are no commits displayed.

Bug reported by Johannes Sixt.
