narrow: drop support for remote expansion (BC)
Previous patches to validate narrow patterns accidentically dropped
support for the include: syntax that allows patterns to be expanded
from a remote.
This feature was never implemented in core and is only implemented on
Google's custom server. Per @martinvonz's review comment in D4522, it
is OK to drop this feature since it isn't used.
The concept of this feature does seem useful. I anticipate it making
a comeback some day in some shape or form. But for now, let's jettison
the dead code.
