I think that all makes a lot of sense.  Three comments below about
this patch in particular.

I agree entirely.  That "Next" button is stupid stupid stupid.
What was I smoking that day?  :-)

I'm concerned about putting them into the Repository menu only
as then the main window is competely void and users are sort of
wondering what they should do next.  I think we should actually
do both.  Put them into the menu and as push buttons on the window.

This string needs to be i18n'd with [mc ...].

Please make a field in this class called say "w_recentlist"
so you can use that field name instead of $w_body.recentlist.
This simplifies the code if we ever have to change the actual path
that the widget resides at, such as to alter the layout.

Why treat this as a Tcl list in a single value?  Why not make it
a true multi-value configuration entry in ~/.gitconfig, like how
remote.$name.fetch is a multi-value entry?  Does Windows allow
you to put " in a path name?  Because the above regex will make
a list of paths that contains " in one of the entries invalid.

I think you also want to have this function return back immediately
if [lsearch $recent $path] >= 0 as then you don't invoke git-config
to perform a no-op change in the configuration file.  As you well
know forking on Windows is a major cost.  We shouldn't run git-config
just because the user opened a recent repository.
