Yes, the X11R6 xterm termcap entry was integrated into termcap.  It
includes ti/te that switch to/from an alternate video page.  

Shortly after this was done, people started complaining about more(1)
and small files.  More was changed not to emit the ti/te strings, as
the same problem would occur on other terminals similar ti/te strings.

If you recompile more, you shouldn't have this problem any more.
