rebase has no --cleanup option

["Дилян Палаузов" <dilyan.palauzov@aegee.org>]

Hello,

in rare cases I want to write commit messages with leading # sign and 
for these messages I call “git commit --cleanup==whitespace”.  So far, 
so good.

Now I want to rebase - modify (edit) the commit message of an old 
commit, or squash a commit, which has leading # in its comment.  I 
cannot pass --cleanup=whitespace and this is the problem description 
here — the #-lines disappear after rebase (edit/squash operations).

In theory I could set the commit.cleanup configuration parameter (in 
.gitconfig), but I prefer not to do this, as I do not want to disable 
permanently the stripping of lines with leading # in git commit 
messages.

Please add --cleanup= option to the rebase command.

I use here the command-line git client 2.39.2, not a GUI or whatsoever.

Kind regards
   Дилян
