term will not scroll in too narrow of a window

[Ben Barrowes <barrowes@lanl.gov>]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I run term with /bin/tcsh in a emacs window.
The prompt is:
alias sp 'set temp = `whoami`; set prompt = "%U$temp%u\@%B%m%b\:\!\:\[%t\]%~\> " '
so it displays the entire path name if not below ~.

If the prompt in the term window (for example split as C-u 6 2 C-x 3) is wider than the
window number of columns, the term window will not scroll past 2 lines. All new
stdout is displayed in the second line overwriting itself. If the prompt display is narrower
than the window, then there is no problem with scrolling, that is, until the prompt becomes
wider than the window, at which point the scrolling bug occurs. This did not happen until I
just upgraded.
