Log message:
        Fix buffer overrun bug.
        * m4/gnulib-cache.m4: Augment with gnulib-tool --import
        xvasprintf.
        * src/format.c [HAVE_EFGCVT]: Delete this code, and use *printf
        variant instead, since [efg]cvt are obsolete and our use of them
        was buggy (savannah sr #104303).
        (format): Fix buffer overflow by using xasprintf.
        * doc/m4.texinfo (Format): Expand format test to catch both bugs.
        * NEWS: Document this fix.
