template: add pad function for padding output

Adds a pad template function with the following signature:

pad(text, width, fillchar=' ', right=False)

This uses the standard python ljust and rjust functions to produce a string
that is at least a certain width. This is useful for aligning variable length
strings in log output (like user names or shortest(node) output).

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)
