Re: [PATCH 2/2] git_path(): handle `.lock` files correctly

SZEDER Gábor [off-list ref] writes:

However, I'm not sure what the right path should be in the first
place, given that each working tree has its own 'logs' directory, but
only for HEAD's reflog, while everything else goes to the main working
tree's 'logs' directory.

As all worktrees should share the same view of where 'master' (for
example) branch points at, what commit it was pointing at before,
etc., the reflogs should also be shared for refs.  The exception is
the HEAD where each worktree can point at its own commit (when detached)
or a branch (when not).

The above "should" does not mean "I know the code works that way so
if your git behaves differently your compiler is wrong"; it just
means "that's the logical conclusion of the basic design, and if
your git does not behave that way, we have a bug (or two)".

Thanks.
