problem with ucb more on Ambassaors

[utzoo!decvax!cca!mclure at sri-unix]

I'm using more with an Ambassador and notice some strange things
happening.  For example, when doing `man more', it forgets to turn off
inverse video on the Ambassador between the last word which requires
it (options in the SYNOPSIS) before the DESCRIPTION paragraph and the
beginning of the word DESCRIPTION.  This leaves the intervening blank
line in inverse video completely.  I tried the same command using a
Datamedia 3025 and it worked perfectly, so something seems amiss with
the inverse video.  I checked /etc/termcap but there appears to be no
padding associated with the so and se modes.
