Severity: wishlist

I just pushed commit 32906819ad to master, which adds
'recentf-show-abbreviated' as a possible value for
'recentf-menu-filter'.  This basically just makes the menu use e.g.
"~/foo" instead of "/home/skangas/foo".

I think this would be a strictly better default than what we have now,
so I suggest we change it.  I'm happy to flip the switch and update
the NEWS entry accordingly.

Please see the attached before/after screenshots.
