You are going in circles, I said such situation was *HYPOTHETICAL*,
Phil Hord said it wasn't, and now you are bringing back more
hypothetical examples, which I would gladly address, as soon as you
accept they are HYPOTHETICAL.

Now, how about you answer the questions about the *REAL* situations
Phil Hord mentioned?

* How many times have you tracked regressions in transport helper's
import/export functionality?

Hint: zero.

* How many times in remote-hg?

Hint: zero.

* How many times has *anybody* done so?

Hint: other than me, quite possibly zero.

And then, before we consider this *hypothetical* situation, it might
be worth noticing what commit this hypothetical person would hit if
you do *not* apply this patch, and what the commit message says:

remote-helpers: add support for an export command

Signed-off-by: Junio C Hamano <gits...@pobox.com>

Yeah, well, glad you didn't apply my patch, wouldn't want to mess up
the code that was clearly explained by that commit message.

And before you rationalize the above commit, because maybe the
functionality was described in the documentation, it wasn't:

 transport-helper.c | 132
 1 file changed, 120 insertions(+), 12 deletions(-)

If you do apply my patch, it turns out even the shortest version of my
commit message already gives more information to this *hypothetical*
developer person.

I partially agree with this, but I think documenting the nuts and
bolts of transport-helper would be better in done in code,
documentation, tests, and mailing list analysis. And in all those
respects, I believe I've done a more than adequate job.
