Probably examples like this could go in a later EXAMPLES section.

At first I was worried about this not actually working, thinking
"push" might have traditionally had the newline-ends-command-stream
semantics that "connect" has.  But the push codepath does not set the
no_disconnect_req flag, so I was worrying in vain. :)  The stream
passed to the helper ends with two newlines when git pushes.

This documents v1.7.7-rc0~61^2~3 (transport-helper: change import
semantics, 2011-07-16).  Such a documentation fix was desperately
needed; thank you!

For what it's worth, with or without a change to prevent the example
from interrupting the flow of description,
