According to 'git gui blame configure.ac', libtool has been using
${a:+b} since July 2004, with no bug reports about a "bad substitution"
from a less-than-stellar shell (in fact, libtool's use dates back to the
days when autoconf didn't even enforce shell function support). Thanks
for this additional anecdotal evidence that autoconf's recent move to
document that : is reliable for null substitutions is reasonable for all
shells that support functions.
