This avoids an unexpected early EOF error in got-fetch-pack.

ok?

-----------------------------------------------
 make got-fetch-http pass "done\n" through rather than faking it
 
 Without this we exit the loop early and got-fetch-pack sees unexpected
 end-of-file on stdout trying to write its final "done\n" message.
