doc: fix want-capability separator

draftcode · gitster · commit 742587662fbd · 2018-07-30T11:25:20.000-07:00
Unlike ref advertisement, client capabilities and the first want are
separated by SP, not NUL, in the implementation. Fix the documentation
to align with the implementation. pack-protocol.txt is already fixed.
