display-buffer attempt to pop-up frame in batch mode causes "Unknown terminal type" error |

Package: emacs
With the current trunk:
./src/emacs -Q -batch README INSTALL Makefile
Loading vc-bzr...
Unknown terminal type
(exits with status /= 0)
OK, this is not a very sensible example, but it illustrates the point.
It's caused by display-buffer trying to pop-up a frame in batch-mode and
is very recent.
Emacs 23 does not have this problem by default, but the following shows
the same issue:
emacs-23.3 -Q -batch --eval '(setq pop-up-frames t)' README INSTALL Makefile

OK, no problem, let's not bother with it then.

If you mean the cus-dep thing, then it was a correct change, independent
of this issue, and should remain.
I'll close this, thanks.
