bookmarks: rely on exception for malformed lines

Since we already have an exception context open, for other thing, we can
simplify the code a bit and rely on exception handling for invalid lines.

Speed is not the main motivation for this changes. However as I'm in the middle
of benchmarking things we can see a small positive impact.

Before:
! wall 0.009358 comb 0.000000 user 0.000000 sys 0.000000 (best of 303)

After:
! wall 0.009173 comb 0.010000 user 0.010000 sys 0.000000 (best of 310)

# 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

    step = int(sys.argv[2])

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

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