Build argument list and environment of child processes by using struct child_process and populating its members "args" and "env" directly instead of maintaining separate strvecs and letting run_command_v_opt() and friends populate these members. This is simpler, shorter and slightly more efficient. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Taylor Blau <me@ttaylorr.com>
