commit 7c476caba56c5d25ac0426d2092b3d00af43913e
Author: Norihiro Tanaka <address@hidden>
Date:   Sat Nov 8 07:49:27 2014 -0800

    tests: avoid awk+printf+\xHH portability trap
    
    * tests/init.cfg (hex_printf_): Rewrite in terms of printf and sed.
    Using awk's printf with \xHH in the format string was not portable
    to the awk of Solaris 10, AIX 7 or HP-UX 11.23, as reported in
    http://debbugs.gnu.org/18987.
    * tests/word-multibyte: Use printf rather than hex_printf_,
    and give the character we're printing a name: e_acute (rather
    than A-grave), since that is used in other tests.
    a trailing \n in the format string, adjust by removing it, and
    instead invoking echo.
    * tests/multibyte-white-space: Simply remove each trailing \n.
    They were not needed.
