Protect directory argument

Fixes an issue where e.g. `pathmenu -- -P' would lead to `cd -P' being
executed causing pathmenu to start in the home directory; or `pathmenu
-- -x' would lead to the invalid option `cd -x' causing cd(1) to fail.

Reword man page to be more consistent

Update man page and usage text

Update dicemenu command suggestions

dicemenu: Return to pathmenu if dice’s dmenu fails

The eval will not take place if the dmenu command in
‘cmd=$(... | dmenu ...)’ fails.

Prior to this patch, dicemenu as a whole would exit immediately
if ESC was pressed in the dice stage.

dicemenu: Don’t suggest less/vi for non-files

dicemenu: remain in the last working directory

dicemenu: Show number of hiddens args in prompt
