Added a note to man page about what happens to information that is
recorded in the private journal. Since it uses Branch.get, that
information will be copied when options allow. It seemed better to allow
it and document it than not allow it, since the options allow excluding
repositories and so can be used to exclude private repos if desired.
init: When annex.commitmessage is set, use that message for the commit
that creates the git-annex branch.
This will be used by filter-branch too, and it seems to make sense to let
annex.commitmessage affect it.
Not tested yet but should work.
Noted a possible optimisation, which should probably be added, to
speed it up in cases where there is no uuid filtering being done.
It would need Annex.Branch to add a function like getRef that uses
catFileDetails, so the sha is also returned. The difficulty would be
making it support the precached file content; if it didn't it would
probably not be any faster and could even be slower. So probably the
precaching would need to be changed to also cache the sha.
This is less erorr-prone, and easier for the user to reason about; it
preserves the man page's promise that only explicitly included
information will be copied.
filterBranch should be reusable for copy-branch command.
Changed LogVariety to differentiate between LocationLog and UrlLog;
only location logs contain uuids and need to be filtered by uuid,
while url logs do not. This does not change current behavior,
but it will let filterBranch be reused without filtering url logs
incorrectly.
This oversight didn't cause any problems because the only place that
uses the information is dropDead, which handles Nothing the same as Just
OtherLog.
ghc 8.8.4 seems to have changed something that broke code that has been
successfully using forkProcess since 2012. Likely a change to GC internals.
Since forkProcess has never had clear documentation about how to
use it safely, avoid using it at all. Instead, when git-annex needs to
daemonize itself, re-run the git-annex command, in a new process group
and session.

Similar to what commit 675556fd9a did for
adding a non-annexed file, this prevents the smudge clean filter
recognising the inode if git add is later run on the unannexed file.
