[GSoC][PATCH v3 0/3] rebase -i: rewrite reflog operations in C

Thes patch series rewrites the reflog operations from shell to C. This is part of the effort to rewrite interactive rebase in C.

The first commit is dedicated to creating a function to silence a command, as the sequencer will do in several places with these patches.

This branch is based on ag/rebase-i-rewrite-todo, and does not conflict with pu (as of 2018-06-21).

Changes since v2:

 - Removing the “verbose” parameter to run_command_silent_on_success()

 - Rewording some parts of the second commit

 - Changing the help for the “--verbose” flag

Alban Gruin (3):
  sequencer: add a new function to silence a command, except if it
    fails.
  rebase -i: rewrite setup_reflog_action() in C
  rebase -i: rewrite checkout_onto() in C
