reimplemented feature in less

[pwolfe at kailand.KAI.COM]

Version 73 of less (-: Why the new version number scheme, Mark?  Trying to
confuse us? :-) had a feature that was eliminated in the recent posting.  The
"e" option still quits the second time you reach end of file, but now if a
single file being displayed that is less than one screen length, less doesn't
exit immediately, but displays it's prompt instead.  I prefered the old
action.

The following patch adds four lines to prim.c to re-implement this feature.
Feed to patch or hand implement if you like.
