drawdag: support obsmarker creation in comments

This patch adds special comment handling so one can create obsmarkers in
drawdag comments like "# replace: A -> B -> C", "# prune: X, Y, Z",
"split: P -> M, N" and they are just self-explained.

# 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

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)
