tests: split capabilities into separate lines while searching for "narrow"
This test is interested only in capabilities that are related to narrow, so
let's omit everything else. Makes it easier to update other capabilities (and
"rev-branch-cache" is one of the usual patterns that are already present in
tests/common-patterns.py anyway).

Test attempting a narrow clone against a server that doesn't support narrowhg.
$ . "$TESTDIR/narrow-library.sh"
$ hg init master
$ cd master
$ for x in `$TESTDIR/seq.py 10`; do
> echo $x > "f$x"
> hg add "f$x"
> hg commit -m "Add $x"
> done
$ hg serve -a localhost -p $HGPORT1 --config extensions.narrow=! -d \
> --pid-file=hg.pid
$ cat hg.pid >> "$DAEMON_PIDS"
$ hg serve -a localhost -p $HGPORT2 -d --pid-file=hg.pid
$ cat hg.pid >> "$DAEMON_PIDS"
Verify that narrow is advertised in the bundle2 capabilities:
$ cat >> unquote.py <<EOF
> from __future__ import print_function
> import sys
> if sys.version[0] == '3':
> import urllib.parse as up
> unquote = up.unquote_plus
> else:
> import urllib
> unquote = urllib.unquote_plus
> print(unquote(list(sys.stdin)[1]))
> EOF
$ echo hello | hg -R . serve --stdio | \
> "$PYTHON" unquote.py | tr ' ' '\n' | grep narrow

Make a narrow clone (via HGPORT2), then try to narrow and widen
into it (from HGPORT1) to prove that narrowing is fine and widening fails
gracefully:
$ hg clone -r 0 --narrow --include f1 http://localhost:$HGPORT2/ narrowclone
