The man(7) package could have keep macros that work like ms(7)'s.

No floats, though.  (We _could_ implement those, but I have a use case for
KS/KE and not for floating keeps.)

The use case is to avoid awkward page breaks in short paragraphs, paragraph
tag series, and tables.

This shouldn't be hard to do, would be helpful for people who care about
paginated typography, and can be utterly ignored by those who don't care. 
Since the macros would interpret no arguments and set up no traps, they
wouldn't cause any regressions.

This isn't utterly trivial to implement because we do already use diversions
for paragraph tags and link text.  On the other hand, nothing in the man(7)
package uses "transparent throughput" (\! or \? escape sequences), so we don't
have the "bubble-up" problem.  I _think_ it will be straightforward.  Time
will tell.
