revset: introduce an internal `_rev` predicate for '%d' usage

In 24a1f67bb75a, we aligned "%d" behavior on "%ld" one, invalid revisions got
silently ignored. However, soon after in 8aca89a694d4 and 26b0a7514f01, a side
effect changed the behavior of "%ld" to no longer silently filter invalid
revisions.

After discussion on the mailing list, it was decided to align on the new %ld
behavior:

https://www.mercurial-scm.org/pipermail/mercurial-devel/2019-January/127291.html

This changeset introduce a '_rev()' predicated that keep the benefit from
24a1f67bb75a while enforcing a more strict checking on the inputs.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
