keyword: inform user about current keywordset in kwdemo

The kwdemo --default output now looks roughly like this:

      configuration using default cvs keywordset
[extensions]
keyword =
[keyword]
demo.txt =
[keywordset] * section added with this change
svn = False
[keywordmaps]
...

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
