[Bf-committers] Cursors, Patches, and Process

Hi Harley,

I personally find it useful to have all the changes in a single diff
for review/testing. The criteria I use is not much in regard to size
though, but to added noise to the review. If the OS specific changes
are isolated in specific files I think it is ok to be a single commit.
That said, before committing you could split it to separate the
original (windows-only) bug fix and further improvements.

Note regarding our current review process: We have no way to create a
review for a branch, and even, to clean that branch up (rebases, ...)
during the review process. That would be a more elegant solution for
cases like yours. In this hypothetical scenario we could see a 1:1
snapshot of what will be merged, with individual commits and their
individual commit messages.

Anyways, one thing you can do, however, is to make sure you either use
arcanist to create/update your patches, or use git diff with context
when submitting them (e.g., `git diff -U100` to include 100 lines
before and after the modified changes).
