AT_KEYWORDS fix

[Ralf Wildenhues]

AT_KEYWORDS([foo bar])
AT_KEYWORDS([baz])

causes bar and baz to be separated by a newline in the output and thus
baz to vanish in `testsuite --help'.  The patch below should fix that.

Regards,
Ralf

        * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
        not newline.
