Addresses this bug report:

    GTK: 'bsdir' doesn't work.  Sometimes get a "gtk critical error".  Moved
    some code to append file name to further down in gui_gtk.c
    gui_mch_browse(), but "last" value of 'bsdir' still doesn't work.

I cannot reproduce the bug -- I never get a "gtk critical error" and the "last"
value of 'bsdir' works.  The last directory remembered by the file browser is
only updated when a file is opened or saved, and I think this what confuses the
author of the report.  If one just opens the file browser, changes to another
directory, and then clicks "Cancel", the remembered last directory isn't
changed.  Looking at the code (message.c:do_browse, gui_gtk.c:gui_mch_browse
and gui_gtk.c:gui_mch_browsedir), I see this behaviour is by design, as the
returned file name from the dialog is simply NULL if a file isn't opened or
saved.  The remembered last directory is taken from the returned file name,
which is of course not possible if the file name is NULL.  I think the correct
solution is to update the 'bsdir' documentation, such that this behaviour of
the "last" value is clear.
