[PATCH] learn: use "spam" as subject for removal commits

[Eric Wong <e@80x24.org>]

Sometimes an email is an innocent removal "rm" for a
misdirected, off-topic post, while most removed messages are
"spam".  Allow anybody to look at history and easily distinguish
the reason for removing the message.
