Any technical reason for discarding this functionality I submitted some
time ago?
I'm using it with the Google Drive API, add seems to be working fine.

Hi,
Bellow I'm sending a OverbyteIcsHttpProt.pas diff file to implement
the HTTP PATCH method ( https://tools.ietf.org/html/rfc5789 )
Some RESTful APIs need this method, so it's handy to have it directly
implemented instead of emulating it with a PUT and later header change
in the OnRequestHeaderEnd event.
