As a general rule of thumb, if the pkt-line is a pack or object, it's
binary, and otherwise (a ref advertisement, a negotiation, etc.) it's
text.  Almost any case where GIT_TRACE_PACKET prints the output is going
to be text, and almost any case where it does not is going to be binary.

Note that whether something is text or binary is specifically an
attribute of what part of the protocol is being parsed, not what bytes
it contains.  For example, a ref advertisement with a ref containing the
bytes FE and FF is text, despite those not appearing in UTF-8.
