match: resolve filesets in subrepos for commands given the '-S' argument
This will work for any command that creates its matcher via scmutil.match(), but
only the files command is tested here (both workingctx and basectx based tests).
The previous behavior was to completely ignore the files in the subrepo, even
though -S was given.
My first attempt was to teach context.walk() to optionally recurse, but once
that was in place and the complete file list was built up, the predicate test
would fail with 'path in nested repo' when a file in a subrepo was accessed
through the parent context.
There are two slightly surprising behaviors with this functionality. First, any
path provided inside the fileset isn't narrowed when it is passed to the
subrepo. I dont see any clean way to do that in the matcher. Fortunately, the
'subrepo()' fileset is the only one to take a path.
The second surprise is that status predicates are resolved against the subrepo,
not the parent like 'hg status -S' is. I don't see any way to fix that either,
given the path auditor error mentioned above.
Source bundle was generated with the following script:
# hg init
# echo a > a
# ln -s a l
# hg ci -Ama -d'0 0'
# mkdir b
# echo a > b/a
# chmod +x b/a
# hg ci -Amb -d'1 0'
$ hg init
$ hg -q pull "$TESTDIR/bundles/test-manifest.hg"
The next call is expected to return nothing:
$ hg manifest
$ hg co
3 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg manifest
a
b/a
l
$ hg files -vr .
2 a
2 x b/a (glob)
1 l l
$ hg files -r . -X b
a
l
$ hg manifest -v
644 a
755 * b/a
644 @ l
$ hg manifest --debug
b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644 a
b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 755 * b/a

$ hg manifest -r 0

$ hg manifest -r 1
a

l
$ hg manifest -r tip
a

$ hg manifest tip

$ hg manifest --all
a

The next two calls are expected to abort:
$ hg manifest -r 2
abort: unknown revision '2'!

$ hg manifest -r tip tip
abort: please specify just one revision
