Escaping of ' is redundant.

I would find easier { and } instead of " and " to prevent so many backslashes
but opinions differ on it, FYI:
    gdb_test_no_output {set $a={'a','b'}}
    gdb_test {printf "%s\n", $a} "ab"


Still this testcase FAILs for me:
printf "%s\n", $a^M
abX^M
(gdb) FAIL: gdb.base/printcmds.exp: printf "%s\n", $a

Where X is some binary unprintable garbage character, not sure which way you
plan to fix it (maybe some `error' call if there is no zero-terminator?).


Thanks,
