git-gui: avoid exception upon Ctrl+T in an empty list
Previously unstaged files can be staged by clicking on them and then
pressing Ctrl+T. Conveniently, the next unstaged file is selected
automatically so that the unstaged files can be staged by repeatedly
pressing Ctrl+T.
When a user hits Ctrl+T one time too many, though, Git GUI used to throw
this exception:
expected number but got ""
expected number but got ""
while executing
"expr {int([lindex [$w tag ranges in_diff] 0])}"
(procedure "toggle_or_diff" line 13)
invoked from within
"toggle_or_diff toggle .vpane.files.workdir.list "
(command bound to event)
Let's just avoid that by skipping the operation when there are no more
files to stage.
