Thanks for this explanation!  I didn't realize that the string "curl"
would change its semantics in the context the deletion of the
submodule/directory, but it makes sense now that you've explained it.

that would be great.  if i have time to do more work on debcargo in the
nearterm, i'll probably start by finalizing the -2 of curl-sys, but if
it takes me ~1 week to get to it, i'll just let you go forward with it
as part of your cargo/debcargo work.

ok, thanks for doing this work, i really appreciate it!
