After some more experimentation I believe I've found the answer: what we
should do is hack the CVS history so that the branch revisions sprout
from the mainline revision that they should logically have sprouted
from, not the chronologically-most-recent revision. When I modify it.po
as shown in the attached patch, I get a conversion that has no funny
business at all: it.po is deleted where it should be, and added where it
should be, and there's *no* manufactured commit anywhere.
Now, when you look at the patch, it's probably going to scare the
daylights out of you. But it's really not that bad. What we're doing
is renumbering the 126.96.36.199 revision to 188.8.131.52 (because it now sprouts
from 1.5 not 1.7 on the mainline) and replacing its delta content with
an appropriate delta from 1.5 not 1.7. The delta content is easily
generated via "cvs diff -n" between the relevant versions --- AFAICT
all we have to do to the diff output is double any @-signs. We can also
easily verify that we did it right, by checking out the branch revision
from CVS afterwards and seeing that it has the right content.
Once I understood what needed to be done, it took me about two minutes
to make these changes manually. I'm inclined to think it's not worth
developing a tool for it --- we could probably manually fix the couple
dozen files that need to be fixed in less time than that would take.
