You can use quadrigraphs:
AC_ARG_WITH(blah, AC_HELP_STRING([--with-blah@<:@=bleh@:>@], [foobar]))
Unfortunately, AC_HELP_STRING does the length check before the
quadrigraphs get squashed, so the help text will often be moved to the
next line when it doesn't actually have to.
AC_HELP_STRING is actually quite nice, IMHO (and will cause user options
to fit in nicely even if a new version of autoconf changes the --help
layout).
