Subject: [PATCH] run-command.c: introduce trace_run_command()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This is the same as the old code that uses trace_argv_printf() in
run-command.c. This function will be improved in later patches to
print more information from struct child_process.
