Here's a quick fix for what's arguably a bug (hence I've flagged it for stable): `hg import` with no arguments aborts quite unhelpfully, as shown by timeless' paste here: <http://pastebin.mozilla.org/1361350>
This patch makes it abort with a useful message when, say, you meant to say `hg import -` but forgot the '-'.
It also quashes the usage text. Not sure if that's consistent with other commands. Bikeshedding and alternate approaches welcome.
[Hopefully Apple Mail doesn't mangle this.]
