This style is overkill for some commands, but it's worthwhile to use the same style to issue all commands, and it's useful to avoid open-coding string lengths. Signed-off-by: Daniel Barkalow <redacted> --- This is really a clarity improvement for the previous series, but it's here to establish the nicer style before introducing more commands. transport-helper.c | 21 ++++++++++++++------- 1 files changed, 14 insertions(+), 7 deletions(-)
