Re: [ANNOUNCE] Git v2.20.0-rc1

Unless I hear otherwise in the next 24 hours, I am planning to merge the following topics to 'master' before cutting -rc2. Please stop me on any of these topics.

 - jc/postpone-rebase-in-c

   This may be the most controversial.  It demotes the C
   reimplementation of "git rebase" to an experimental opt-in
   feature that can only be enabled by setting rebase.useBuiltIn
   configuration that defaults to false.

   cf. <xmqq36roz7ve.fsf_-_@gitster-ct.c.googlers.com>

 - ab/format-patch-rangediff-not-stat

   The "--rangediff" option recently added to "format-patch"
   interspersed a bogus and useless "--stat" information by mistake,
   which is being corrected.

   cf. <xmqqa7lz43d8.fsf@gitster-ct.c.googlers.com>

The following three topics I do not need help in deciding; they are all good and will be merged before -rc2.

 - jk/t5562-perl-path-fix

   This is to invoke a perl scriptlet with "$PERL_PATH" in one of
   the new tests, instead of relying on (an incorrect) she-bang line
   in the script file.

 - tb/clone-case-smashing-warning-test

   This enables the test to see the behaviour of "git clone" after
   cloning a project that has paths that are different only in case
   on MINGW (earlier it wanted CASE_INSENSITIVE_FS prerequisite and
   in addition not on MINGW).

 - nd/per-worktree-ref-iteration

   This fixes a "return function_that_returns_void(...)" in a
   function that returns void.

Thanks.
