[sr-dev] {s.escape.param} transformation

[Camille Oudot]

Hi,

I've noticed that {s.escape.param} doesn't change "@" into "%40", and
yet RFC3261 specifies pvalue as

pvalue            =  1*paramchar
paramchar         =  param-unreserved / unreserved / escaped
param-unreserved  =  "[" / "]" / "/" / ":" / "&" / "+" / "$"

with:
      unreserved  =  alphanum / mark
      mark        =  "-" / "_" / "." / "!" / "~" / "*" / "'"
                     / "(" / ")"
      escaped     =  "%" HEXDIG HEXDIG

I've committed a patch in coudot/escape-param branch to fix the escape
function. Several unreserved characters were escaped, and some reserved
ones weren't.

Regards
