Re: [GSoC][PATCH v3 05/13] sequencer: add a new function to silence a command, except if it fails

> This adds a new function, run_command_silent_on_success(), to
> redirect the stdout and stderr of a command to a strbuf, and then to run
> that command. This strbuf is printed only if the command fails. It is
> functionnaly similar to output() from git-rebase.sh.

> run_git_commit() is then refactored to use of
> run_command_silent_on_success().
