Nit: mostly from my lack of understanding, but until I read the code, I
couldn't understand what 'command' meant in this para. Maybe some
preface would be nice here.

Right, this commit in itself looks good. But I was curious why we need
this, so I did a sneak peak into the following commits.
To summarize, we want to call:
`write_command_and_capabilities(..., "object-info");`
in the upcoming patches to get the object-info details from the server.
But isn't this function too specific to the "fetch" command to be
generalized to be for "object-info" too?
Wouldn't it make sense to add a custom function for 'object-info' in
'connect.c'? Like how we currently have `get_remote_bundle_uri()` for
'bundle-uri' and `get_remote_refs` for 'ls-refs'?
