help: properly document the default pattern

The default isn't to glob. It's relpath, which does no globbing at
all. Thus most commands and options like -X/-I and hg files require
`glob:` in front of them to actually do any globbing.

I think long ago the default was to glob, but that hasn't been true
for a long time.
