Interactive rebases are implemented in terms of cherry-pick rather than
the merge-recursive builtin, but cherry-pick also calls into the recursive
merge machinery by default and can accept special merge strategies and/or
special strategy options. As such, there really is not any need for
having both git-rebase--merge and git-rebase--interactive anymore.
Delete git-rebase--merge.sh and have the --merge option call in to
git-rebase--interactive. Add one new variable ($actually_interactive) to
help keep cases separate, and adjust the detection of the special
circumstances under which a rebase boils down to a simple fast forward so
that it keeps working with the new structure.
Note that this change fixes a few known test failures (see t3421).
testcase modification notes:
t3406: --interactive and --merge had slightly different progress output
while running; adjust a test to match
t3420: tests of precise output while running, but rebase--am,
rebase--merge, and rebase--interactive all were built on very
different commands (am, merge-recursive, cherry-pick), so the
tests expected different output for each type. Now we expect
--merge and --interactive to have the same output.
t3421: --interactive fixes some bugs in --merge! Wahoo!
t3425: topology linearization was inconsistent across flavors of rebase,
as already noted in a TODO comment in the testcase. This was not
considered a bug before, so getting a different linearization due
to switching out backends should not be considered a bug now.
t5407: different rebase types varied slightly in how many times checkout
or commit or equivalents were called based on a quick comparison
of this tests and previous ones which covered different rebase
flavors. I think this is just attributable to this difference.
