reconcileStaged was doing a redundant scan to scannAnnexedFiles.
It would probably make sense to move the body of scannAnnexedFiles
into reconcileStaged, the separation does not really serve any purpose.

This is quite a subtle edge case, see the bug report for full details.
The second git diff is needed only when there's a merge conflict.
It would be possible to speed it up marginally by using
--diff-filter=Unmerged, but probably not enough to bother with.

It makes sense to keep the key used by the old version of an
associated file, until the merge conflict is resolved.
Note that, since in this case git diff is being run with --index, it's
not possible to use -1 or -3, which would let the keys
associated with the new versions of the file also be added. That would
be better, because it's possible that the local modification to the file
that caused the merge conflict has not yet gotten its new key recorded
in the db.
Opened a bug about a case this is thus not able to address.

* drop: When two files have the same content, and a preferred content
expression matches one but not the other, do not drop the file.
* sync --content, assistant: Fix an edge case where a file that is not
preferred content did not get dropped.
The sync --content edge case is that handleDropsFrom loaded associated files
and used them without verifying that the information from the database was
not stale.
It seemed best to avoid changing --want-drop's behavior, this way when
debugging a preferred content expression with it, the files matched will
still reflect the expression. So added a note to the --want-drop documentation,
to make clear it may not behave identically to git-annex drop --auto.
While it would be possible to introspect the preferred content
expression to see if it matches on filenames, and only look up the
associated files when it does, it's generally fairly rare for 2 files to
have the same content, and the database lookup is already avoided when
there's only 1 file, so I did not implement that further optimisation.
Note that there are still some situations where the associated files
database does not get locked files recorded in it, which will prevent
this fix from working.
