Am I wrong if I say that dry run is for commands that modify something? For
example there is no "diff --dry-run" probably because diff does not change
anything. A dry run has no real meaning for diff.

This the same for "git remote show": it's a read-only command, it just display
a summary of the remote and does not modify anything. With -n, it just skips
the ls-remote (read-only) step and yes the result can be different, some parts
can be missing. Exactly like "route -n", we skip the dns resolution, the host
names are missing.

Now, if we talk about "prune", I completely agree. A --dry-run flag make sens.
But it's not the same thing than the "show -n" one. For what reason would I
want to ask "prune" to skip the ls-remote step? What I would find more useful
is to make "prune" show what it is doing (like "update") and add a --dry-run
option to say "just show me, but do not touch anything". And we can even add a
-p flag to "update" to say "prune at the same time".

Will fix. (my tabs were only 4 spaces long)

I don't understand. Is it ok or not?

Thanks for your comments,
