What is the difference between these two errors?
I know they are generated in different circumstances, but that's not the point.
They mean the same thing, don't they? "The path is locked and no (correct)
lock tocken has been supplied."
We need either to clarify the difference between these, or to merge them into a
Aha! I have just seen that "SVN_ERR_FS_PATH_LOCKED" is tested by the macro
"SVN_ERR_IS_LOCK_ERROR", and therefore perhaps is intended only to mean, "You
can't lock this path because it is already locked". If that's the case, may we
rename it to "SVN_ERR_FS_PATH_ALREADY_LOCKED"? Or at least document it as such.
(By the way, I am looking at this from the point of view that everything -
including each error code - should have an inherent meaning that is known and
documented, rather than its meaning just being considered to be "whatever the
code that currently uses it wants it to mean".)
Related to this is the following code in subversion/libsvn_ra_dav/commit.c:

That "if" is trying to say, "if (an error occured that might be resolved by
sending all the lock tokens held under this directory)". However, it doesn't
appear to be checking the most appropriate set of error codes. Neither
SVN_ERR_FS_BAD_LOCK_TOKEN nor SVN_ERR_FS_LOCK_OWNER_MISMATCH will be resolved
just by sending more tokens, so there's no point in them being in the list.
And if I'm right about the meaning of SVN_ERR_FS_PATH_LOCKED, then it shouldn't
be there either.
