If $TERMCAP contains the terminal description and NOT the path of the
termcap file, AND $TERM is not the same terminal as the description then
/etc/termcap should be used to find the new description.  This was not
happening.  GNUtermcap was still trying to open the first part of the
description as a file.  This came to light using the program xterm.

Xterm running as a vt100 had already loaded the vt100 description into
$TERMCAP.  From the shell inside xterm we tried to run "xterm -t" which
starts up a tektronix 4014 window, so xterm needed to search for the
4014 entry in /etc/termcap.  Unfortunately it never looked there, but
tried to open "vs|xterm|vs100|xterm" and then reported
"xterm:  unable to find usable termcap entry."

This was fixed by modifying line 410 of termcap.c.  If the code reaches
this line then tem must by NULL or point to a file.  If it contains a
usable entry then we have previous executed "goto ret".
