Currently, if any server options are specified during a protocol v2
fetch, server options will be sent before "command=fetch". Write server
options to the request buffer in send_fetch_request() so that the
components of the request are sent in the correct order.
The protocol documentation states that the command must come first. The
Git server implementation in serve.c (see process_request() in that
file) tolerates any order of command and capability, which is perhaps
why we haven't noticed this. This was noticed when testing against a
JGit server implementation, which follows the documentation in this
regard.
