OK, not "margin".  But what, then?  I tried for some time to come up
with something better that would still fit into a ~78 character first
line of the doc string for the new customisable variable.  So far, I've
had this:

"If non-nil, try to show parens when point is in LH or RH margin."

Maybe I could omit the "try to ".  Maybe I should.  How about something
like:

"If non-nil, show parens when point is before or after the line's code."

?  It's a bit clumsy, though.

As for the name "show-paren-when-point-in-margin", that would have to
become "show-parens-when-point-outside-code", or something, which isn't
quite accurate (sometimes, short comments are inside a line of code),
and isn't very nmonic.

Hmm.  Or, perhaps we could just admit this, and allow "margin" to be
used loosely whenever appropriate.  ;-).
