Fix testsuite errors due to shell quoted parameter expansion issue.

[Ralf Wildenhues]

Interesting shell unportability:

$ bash -c 'f=" val" e=; echo "$e"$f'
val
$ ksh -c 'f=" val" e=; echo "$e"$f'
 val

ksh93, dash, zsh all do it like ksh.  Is that a bug in bash?

Anyway, the patch below seems to fix it, but I may want to fix the log
entry to pinpoing the culprit correctly.

Thanks,
Ralf

    Fix testsuite errors due to shell quoted parameter expansion issue.
    
    * tests/getopt-m4sh.at (_LT_AT_GETOPT_M4SH_SETUP): Insert space
    between double-quoted and unquoted shell parameter, as ksh may
    add one in its output anyway if the expansion of the second one
    starts with a space.
    (short option splitting, enhanced shell short option splitting)
    (long option splitting, XSI long option splitting): Add space in
    expected output.
    Fixes testsuite failures on AIX, FreeBSD, etc.
