[reSIProcate] Invalid parsing of UnknownHeaders (f.e. added via ExtensionHeader mechanism) with the same prefix

[Dmitry Semyonov <dsemyonov@xxxxxxx>]

Hi All,

reSIProcate allows to construct and send messages containing headers 
like:

  P-aaabbb: str1
  P-aaa: str2

(i.e. where the latter header is a prefix of the former one).
The problem is that the headers are converted into:

  P-aaabbb: str1, str2

by reSIProcate on the receiving side.


Please apply the patch that fixes this bug:
