help: merge revsets.txt into revisions.txt

Selecting single and multiple revisions is closely related, so let's
put it in one place, so users can easily find it. We actually did not
even point to "hg help revsets" from "hg help revisions", but now that
they're on a single page, that won't be necessary.

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
