Recently, caa81452f4 relaxed the condition for Snappy pinning a post
from `body.startswith(':#marseypin:')` to the same sans trailing colon.
I believe this was intended to allow :marseypin2: to also lead to post
pinning. However, the amusing, though incorrect, side effect is that
:marseypinkcat: and :marseypinochet: can now also lead to Snappy pins.
This has been remedied by explicitly defining the two conditions we
want rather than hoping all :marseypin [sic] are about pinning.
