Currently it only displays explanations of options like --in and --copies.
In the future, it should explain preferred content expression evaluation
and other decisions.
The explanations of a few things could be better. In particular,
"standard" will just appear as-is (or as "!standard" if it doesn't
match), rather than explaining why the standard preferred content expression
for the group matches or not.
Currently as implemented, it goes to stdout, and so commands like
git-annex find that have custom output will not display --explain
information. Perhaps that should change, dunno.

explain is a kind of debug message, but not formatted in the same way.
So it makes sense to reuse the debug machinery for it, since that is
already quite optimised.

While avoiding most unncessary parens.
Once case where unncessary parens are not avoided is:
not ( ( not foo and baz ) )
It would be good eventually to remove doubled parens like these.

This is to be used to explain why something did or didn't match.
Note that this reimplements match in terms of matchMrun.
Implementing match' as a Writer and matchMrun' as a MonadWriter
resulted in nearly identical implementations, which collapsed into the
same thing thanks to Writer being WriterT Identity.
MAnd and MOr implement short circuiting. So an expression
like "not (foo and bar)" will be explained as [MatchedNot, MatchOperation "foo"]
when foo does not match; whether bar matches is irrelevant. Similarly
"foo or bar" will be explained as [MatchedOperation "foo"] when foo
matches. It seems like that will keep the explanations more
understandable. But also, matchMrun already did short circuiting, and it
could be considerably more work to check if bar matches in these cases.
Note that the type signature of matchMrun changed, but it was
over-generic before.
Note that these changes are licensed under the AGPL. Changed module
license accordingly.

As was recently done with the directory special remote.
Note that the top directory passed to removeDirGeneric was changed to
avoid deleting .git/annex or .git/annex/objects if they ended up empty.

Failure to remove is not treated as a problem, and no permissions
modifications are done, to avoid unexpected states.

* S3: Amazon S3 buckets created after April 2023 do not support ACLs,
so public=yes cannot be used with them. Existing buckets configured
with public=yes will keep working.
* S3: Allow setting publicurl=yes without public=yes, to support
buckets that are configured with a Bucket Policy that allows public
access.
