Log message:
        * ltdl/m4/gnulib-cache.m4: Augment with `gnulib-tool --import
        xvasprintf'.
        * modules/format.c (includes): Use xvasprintf.h.
        (format): Make static.  Avoid buffer overflow, that can lead to
        arbitrary code execution exploit.  Only pass unsigned char to
        is*().  Support F, g, and G specifiers.
        * doc/m4.texinfo (Format): Expose buffer overrun bug.  Document
        new specifiers.
