Hi, 

   I think there are some problems with this patch. Windows users will be
not too happy with this (which may even segfault when the path is longer
than 20 chars). Maybe this is a problem also on VMS and OS/2.

   Some time ago I wrote a simple patch to add '%d' format to
set_status_line, to put the full path. As you (or John Skilleter) noticed,
this is annoing when the path is too long. So I took some ideas from John's
patch, And wrote this one. The main difference is that this patch doesn't
try to parse long paths, instead it simply takes the last part, and puts
three dots at the beginning. Also these new formats are only for the
directory part, so you should use %d%f or %D%f.
(I'm still not happy with the hard encoded maximum length, but changing this
to allow '%20D' formats seems overkill...).
