* extfs/hp48: Added an usage summary. The HP48 external filesystem was
contributed by Christofer Edvardsen <ce@earthling.net>.
* subshell.c (init_subshell): Added ':q' to $cwd in the precmd for
tcsh. It prevents command and filename substitution (e.g. for
a directory named "[word] words")
* view.c (view_done): Set monitor off before deleting the view
file dialog.
