Now a FAQ pointer (improving earlier fiddling about finding
something satisfying between "fussy" and "sloppy", sorry):

Somewhere in the middle of
http://www.tex.ac.uk/cgi-bin/texfaq2html?label=overfull
playing with \tolerance is explained.

Sorry for my earlier idea of \nobreakf, which just saves you from
typing the curly braces of \mbox; however, curly braces are a
nuisance on PC keyboards indeed. And the ordinary \nobreak
after =' suffices as well (TeXbook p. 174).

With "shortish terms" in mathematical formulas, not to be broken,
while the relation may be broken, you could add \nobreakbin
inside them, after
\makeatletter
\newcommand{\nobreakbin}{\binoppenalty\@M}
\makeatother

(... feel somewhat obliged to continue Robin's FAQ pointers
... just playing with Scott Pakin's Visual FAQ
... these FAQ pages are great in briefly surveying possibilities
of dealing with a certain problem, instead of longwindedly
explaining certain commands or packages
... indeed, Karl, "notably \tolerance"!)
