tst-help IndexError

[elianearaujo]

When i was running tst-help, i got the message on the standard output:

Traceback (most recent call last):
  File "/Users/ea/.tst/bin/tst", line 336, in <module>
    identify_and_run_command(args)
  File "/Users/ea/.tst/bin/tst", line 307, in identify_and_run_command
    run_internal_command(args)
  File "/Users/ea/.tst/bin/tst", line 39, in tst_help
    print("  %-12s%s" % (cmd, get_one_line_help(cmd)))
  File "/Users/ea/.tst/bin/tst", line 256, in get_one_line_help
    return stdout.strip().splitlines()[0]
IndexError: list index out of range

obs: I have a custom command installed on my tst environment.
