No. Locking is independent of update. There is no reason whatsoever to
run update on a locked target. It won't unlock it - ever.

No need. Stronger: No reason. Locking is independent of updating;
there simply is no relation other than that they may concern the same
path in the same (virtual) filesystem.

If a file can't be merged, this is where your error is: your workflow
conflicts with the type of file you're chaning. You need to lock the
file before editing it. No need to check for locks: 'svn lock' will
tell you someone else has the file locked already, all this means
you're doing *more* work than required, not less. If you were to lock
the files before editing them, instead of "update", "status", "lock",
"update", you could do with "lock", "update". Clearly this is less
