minirst: detect bullet lists using asterisks

Previously, the "bullet" regular expression excluded the asterisk
('*') as a character denoting a bulleted list. Why I'm not sure
because the asterisk seems to be the canonical bullet character
in reST these days.

This patch makes asterisk-prefixed lines parse as bulleted lists.

'''helper extension to measure memory usage

Reads current and peak memory usage from ``/proc/self/status`` and
prints it to ``stderr`` on exit.
