[PATCH v3 1/3] remote-curl: use strlen() instead of magic numbers

[Denton Liu <liu.denton@gmail.com>]

When we are dealing with a packet-line length header, we use the magic
literal `4`, representing the length of "0000" and "0001", the packet
line length headers. Use `strlen("000x")` so that we do not have to use
the magic literal.
