/appl/lib/wmlib.b [inferno]

[Boyd Roberts boyd@france3.fr]

i've added a few lines to /appl/lib/wmlib.b so that getfilename tracks
the last directory where a file was opened.  passing "" for the
directory argument uses the previous directory where the file was
found.  if "" is passed on the first call "." is used.

to exploit this i changed /appl/wm/edit.b:

18a19,21
> include "lib.m";
>       str: String;
>
69a73
>       str = load String String->PATH;

<               fname := wmlib->getfilename(screen, ed, "", "*", ".");
---
>               fname := wmlib->getfilename(screen, ed, "", "*", "");
268a273,274
>       (nil, f) := str->splitr(curfile, "/");
>       wmlib->taskbar(ed, f);

this patch also includes setting the taskbar to be the basename of the
file currently being edited.  i guess you could say i'm actually writing
limbo with edit.  i'd prefer sam, but i'm beginning to live with edit.
