Hmm ... I grant your use-case for this, but I think the patch
is too narrow-minded, because it supposes that the only string
anybody could wish to output between \watch commands is "\f\n".
Once you open the floodgates of inserting formatting there,
ISTM that people might want other things.
Also, I'm not that thrilled with treating this as a \pset option,
because it has nothing to do with formatting of normal query
results. (IMV anyway, perhaps others will disagree.)
How about instead of defining fixed semantics, we invent a psql
special variable that can contain a string to be output between
\watch commands? It looks like you could then set it through
a command like
\set WATCH_SEPARATOR '\f\n'
(not wedded to that variable name, it's just the first idea
that came to mind)
Personally I'd not bother with inventing a specialized command-line
option to set it, either. There's already -v and friends.

Or we could invent WATCH_BEFORE and WATCH_AFTER ...
