Thanks for a fix.  Queued.

[PATCH] rebase -p: fix incorrect commit message when calling `git merge`.

[gregory . herrero]

From: Gregory Herrero 

Since commit dd6fb0053 ("rebase -p: fix quoting when calling `git
merge`"), commit message of the merge commit being rebased is passed to
the merge command using a subshell executing 'git rev-parse --sq-quote'.

Double quotes are needed around this subshell so that, newlines are
kept for the git merge command.

Before this patch, following merge message:

"Merge mybranch into mynewbranch

Awesome commit."

becomes:

"Merge mybranch into mynewbranch Awesome commit."

after a rebase -p.
