[PATCH] searchmsg: allow lines (and bytes) to be zero

[PATCH] searchmsg: allow lines (and bytes) to be zero

[Eric Wong]

We will occasionally see legit messages with zero lines,
be sure we index that count for NNTP clients.

I'm not sure about bytes being zero (aside from purged
messages), but we should've dealt with that earlier up
the stack.
