Subject: [PATCH] TT#81700 generate_test_tt2.pl should escape `+' in Accept:
 header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Script bin/generate_test_tt2.pl is not able to generate proper regexp
from a mixed Accept header field like for example:

Accept: application/pidf+xml

In this case there is no substitution and the final .tt2 file
does not escape the `+' sign causing the following test to fail
even if user agent are sendind the correct header.
