This rewrites setup_reflog_action() from shell to C.
A new command is added to rebase--helper.c, “setup-reflog”, as such as a
new flag, “verbose”, to silence the output of the checkout operation
called by setup_reflog_action().
The shell version is then stripped in favour of a call to the helper. As
$GIT_REFLOG_ACTION is not longer set at the first call of
checkout_onto(), a call to comment_for_reflog() is added at the
beginning of this function.
