Running streamline_config.pl as it's shown it in the comment header,
you will get a warning about $ksource being uninitialized.  This is
because $ksource is set to ARGV[0], but the examples don't require any
arguments.  Fix by setting ksource to . if no ARGV[0] is given.

This also fixes passing a config file to the script.  For example,
without this is if you run streamline_config.pl . config.old, it will
ignore config.old and try to read .config anyway.  With this change it
will read config.old instead of .config -- which appears to be the
intent of the code.

I have nothing against this change, but I'm confused by how it fixes the
above issue about reading config.old.

Without the patch, passing in both '.' and 'config.old' as parameters,
wouldn't that still set $ksource to '.' and $kconfig to config.old?

Perhaps, it failed for you without passing the '.', which would set
$ksource to config.old. Maybe the real change should be to count the
number of parameters to determine what $kconfig and $ksource get set to?

You're right, I remembered the warning and the bug I encountered, but
forgot that this patch only addresses the warning.

The problem is that if you do  streamline_config.pl . config.old, it
doesn't read config.old at all -- it still reads .config.

OK, I'll take these patches as is, and fix the change log to not talk
about that issue.

You can send another patch that fixes the issue if you like.

I'll queue them up for 3.7.
