Hi,

It seems to me that bash's posix mode should include enabling
xpg_echo mode, in accordance with the SUSv3/POSIX XSI
requirements.

    $ echo 'echo "a\\b"' | bash --posix
    a\b

    $ echo 'shopt -s xpg_echo ; echo "a\\b"' | bash --posix
    a

    $ echo 'shopt -s xpg_echo ; echo "a\\b"' | bash
    a

Thanks,
#233317#10

Remember that bash also goes into posix mode when invoked as `sh'.
I will think about doing it for --posix only; perhaps for `set -o
posix' also.
