format isn't used very much in the autotools:

m4 branch-1_4:
currently %c is undocumented, and no existing examples use it
no examples use \

m4 head:
one example uses it, but when I wrote that example earlier
this year, I found it clunky, so I have no qualms changing it
no examples use \

autoconf:
lib/autotest/general.m4 - %d and %s, no \
lib/m4sugar/m4sh.m4 - %s, no \

automake:
not found

libtool:
not found

gnulib/m4:
not found

OK, no overengineering necessary. :)  I'll have the patch ready within
the week.
