Right, that is the "dup" I was thinking of. Anyway, I think René's
"xstrfmt" is my favorite of the suggestions, and you seemed to like it,
too. Here is a re-roll using that name.
The first two patches are the same except for the name change. The rest
are more applications of it (and other techniques) found by grepping for
"malloc.*strlen". The diffstat is very encouraging, and I think the
results are much more readable (in addition to being more obviously
correct). The last two also fix real "bugs", but I doubt either is a
problem in practice.
