Why is configure.ac not fixable? E.g., in this patch:

+	      AC_HELP_STRING([--enable-stack-protector=@<:@yes|no|all|strong@:>@],
+			     [Use -fstack-protector[-all|-strong] to detect glibc buffer overflows]),


The commentary can contain folded lines without problem (the extra indenting is removed), and the first line can be moved down, e.g.,

   AC_HELP_STRING(
     [--enable-stack-protector=@<:@yes|no|all|strong@:>@],
     [Use -fstack-protector[-all|-strong] to detect glibc
      buffer overflows]),
