I definitely like these new names. "--manual" describes the use case:
I did a manual merge; please update the merge metadata for me.
"--record-only" describes what svnmerge.py actually does -- it records
that we already did a manual merge. Both names are good, with the
first being shorter, and the second being slightly more clear. Like
you, I tend to favour clarity over brevity.

Very clear. Great! Thanks for writing this documentation as it will be
very helpful for users.
Should we also refer back to the "block" subcommand, which allows you
to ask svnmerge *not* to merge a particular set of revisions? In some
cases, if you didn't exactly "merge" the revision but the
functionality is available on the branch with similar code, it might
be tough to choose between the two.
We may want to mention somewhere that svnmerge.py does not record
"indirect" metadata (i.e. it does not record that, if you merge a
change from branchA to branchB, you might indirectly be merging
changes from trunk). For now, you can correct this metadata using
merge --record-only. In future, it might be possible for us to be a
bit better about merging the indirect metadata, but I don't think
we'll ever get it perfect, so this feature will always be handy.

Great! Good idea to refer back to "--record-only".

Really? Why would --record-only allow svnmerge.py to behave more
correctly? I find this sentence a bit confusing. I think we should
simply say that "--record-only" records that a merge happened, whereas
"block" records that a merge should not happen.
