Merge branch 'pw/rebase-i-cleanup-fix' into maint-2.51

"git rebase -i" failed to clean-up the commit log message when the command commits the final one in a chain of "fixup" commands, which has been corrected. * pw/rebase-i-cleanup-fix: sequencer: remove VERBATIM_MSG flag rebase -i: respect commit.cleanup when picking fixups
