Teach rebase -i about --preserve-merges
The option "-p" (or long "--preserve-merges") makes it possible to
rebase side branches including merges, without straightening the
history.
Example:
X
\
A---M---B
/
---o---O---P---Q
When the current HEAD is "B", "git rebase -i -p --onto Q O" will yield
X
\
---o---O---P---Q---A'---M'---B'
Note that this will
- _not_ touch X [*1*], it does
- _not_ work without the --interactive flag [*2*], it does
- _not_ guess the type of the merge, but blindly uses recursive or
whatever strategy you provided with "-s <strategy>" for all merges it
has to redo, and it does
- _not_ make use of the original merge commit via git-rerere.
*1*: only commits which reach a merge base between <upstream> and HEAD
are reapplied. The others are kept as-are.
*2*: git-rebase without --interactive is inherently patch based (at
least at the moment), and therefore merges cannot be preserved.
