If this was true, than vdelta should *not* have been anywhere on the
profiles, since *nothing* but imports was done.
Thus, nothing but "HEAD" revisions should exist.
This is what i meant by "the first".
I have no idea why Ollivier felt the need to confuse the issue by
trying to pretend that i don't know what CVS does (I wasn't actually
asking, even though it looked like it). It's rather obvious that in an
import into an empty repository, the "first revision" is the "HEAD
revision", as it is the *only* revision. We aren't caring about what it
does when you have more than one revision, as this is *not* the test
that was run.
But, given what you say, and that vdelta *was* the biggest time user,
one of the following must hold:
1. You are wrong, and we are supposed to be storing everything
non-fulltext (deltas against itself)
2. Subversion is buggy, and it is storing non-fulltext when it
shouldn't be
3. Subversion is buggy, and it is doing deltas and throwing them away.
