>Description:
	

	Jove's 'shell' command is supposed to create a window, allocate a
	pty and start a shell therein.  Instead, it creates the window and
	prints "[Out of ptys!]" on jove's main status/manual command line.

	NOTE 1:  'screen' does not seem to have this issue.
	NOTE 2:  Also fails for the super-user, so it is not a permissions
		problem.

>How-To-Repeat:
	build and install jove
	jove (filename optional)
	ESC x shell
	see bottom line
>Fix:
	No fix for this one.
