Executing .KS after .1C exhibits a bug.
Instead on the next page, the text between .KS and .KE is shown at
the bottom of the page (where footnote would be).
To reproduce the bug: http://sprunge.us/xyCUX7
The bug can be fixed by changing two lines in tmac.s:
if \\n(NX<1 .bp\}
to
if \\n(NX<=1 .bp\}
and
if \\n(NX<1 'bp\}
to
if \\n(NX<=1 'bp\}
