help: pass subtopic into help()

Now that we have multiple directories where help topics can live,
we need a mechanism to access them. We already use "." to
separate topic from section. So it seems logical to also use "." to
denote the sub-directory of a topic.

This patch teaches the help command to parse out the possible
sub-topic and pass it to the help system.

# A portable replacement for 'seq'
#
# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP

import sys

start = 1
if len(sys.argv) > 2:
    start = int(sys.argv[1])

step = 1
if len(sys.argv) > 3:
    step = int(sys.argv[2])

stop = int(sys.argv[-1]) + 1

for i in xrange(start, stop, step):
    print i
