Show the containing directory instead of the full path in the recent repos menu

The third column of the recent repos menu spells out the full path of
each repo. That repeats the directory name which the first column
already shows, and it writes out the home directory in full. Both are
wasted width in a menu that is limited to 90 columns; the path column is
the first thing to run off the right edge, and users who don't know that
'L' scrolls the menu horizontally never see it at all.

Show the directory that contains the repo instead, with the home
directory abbreviated to '~'. For a list of 106 recent repos this takes
the column from 111 characters down to 97 at its longest, and from 47
down to 28 in the median.
