--backend is no longer a global option, and is only accepted by commands
that actually need it.
Three commands that used to support backend but don't any longer are
watch, webapp, and assistant. It would be possible to make them support it,
but I doubt anyone used the option with these. And in the case of webapp
and assistant, the option was handled inconsistently, only taking affect
when the command is run with an existing git-annex repo, not when it
creates a new one.
Also, renamed GlobalOption etc to AnnexOption. Because there are many
options of this type that are not actually global (any more) and get
added to commands that need them.

Handles keys that are substrings of other keys, as well as pointer files
that contain a newline after the key.
Note that -S does not match regexp, while -G does by default. Docs are
not clear, determined experimentally. The only other difference in
changing to -G is that if a file used to contain the key and changed
in some way, while still containing the key, -G will match and -S would
not. So eg, annex links that git annex fix rewrites will match, and
files that change lock status will match. Which is an improvement anyway.

Does not check the reflog, but otherwise works.
It's possible for it to display something that is not an annexed file,
if a non-annexed file somehow ends up containing something that looks
like the key's name. This seems very unlikely to happen, and it would
add a lot of complexity to detect it and somehow skip over that file,
since the git log would need to either be run again, or not limited to 1
result and canceled once enough results have been read.
Also, it kind of seems ok, if a file refers to a key, to consider that
as a place the key was used, for some definition of used. So, I punted
on dealing with that. May revisit later.
