avoid panic save panic if external compress fails

Browse Source 
On OSX 10.5, save file compression and uncompression fail when I run
under debugger control (for gdb, at least; I don't know why).  I used
'#panic' to try something out.  panic() calls exit_nhwindows(), then
after some messages calls dosave0().  Saving calls docompress_file()
and when that fails on tty it tries to call clear_nhwindow(WIN_MESSAGE)
but WIN_MESSAGE has been torn down already, leading to a nested panic().
Avoid the call to clear_nhwindow() if windows aren't up.
