I think it makes sense.
I wanted to preserve the error message, because the description of
'--sort=<key>' in 'Documentation/git-ls-remote.txt' explicitly
mentions it, and I added the condition at this place because I didn't
want to duplicate the construction of the error message.
However, if we go for a more informative error message, then wouldn't
it be better to add this condition in populate_value() before it even
calls get_object()? Then we could also add the problematic format
specifier to the error message (I think, but didn't actually check),
just in case someone specified multiple sort keys.
