[PATCH v3 4/4] git gui: allow for a long recentrepo list

[Philip Oakley <philipoakley@iee.org>]

The gui.recentrepo list may be longer than the maxrecent setting.
Allow extra space to show any extra entries.

In an ideal world, the git gui would limit the number of entries
to the maxrecent setting, however the recentrepo config list may
have been extended outwith the gui, or the maxrecent setting changed
to a reduced value. Further, when testing the gui's recentrepo
logic it is useful to show these extra, but valid, entries.
