DOC: http header capture has not been limited in size for a long time

It's been documented for a very long time that captured HTTP headers
were limited to 64 characters, but this has not the case anymore since
1.3.11 in 2007 (commit cf7f320f), as they all use their own pool and
have no such limit anymore.

This fix should be backported to 1.4 and 1.3.
