update? upload?

I somehow thought that dumb HTTP walker support was on the chopping
list for Git 3.0 but apparently it isn't, so updating this remote
corner of the system I thought nobody cared about is a good thing.

I personally feel that from here ...

... to here are way too verbose and unnecessary.

"set as NULL" -> "set to NULL"?

   ... and then early in the function, "parse_options()" call will give
   the options help and exit, without having to consult much of the
   configuration file.  So it is safe to omit reading the config
   when `repo` argument the caller gave us is NULL.

and that would be sufficient.  All the rest of the proposed commit
log message can also be removed, I think.

Thanks.
