Summary: Too eager percent-encoding

Initial Comment:
Current behaviour:

% http::mapReply "._~-"
%2e%5f%7e%2d


Background:

RFC3986 Section 2.3:
"-- percent-encoded octets in the ranges of ALPHA
(%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D),
period (%2E), underscore (%5F), or tilde (%7E) should
not be created by URI producers --"


Desired behaviour:

% http::mapReply "._~-"
._~-


Possible fix:

From http.tcl in procedure http::init line
if {![string match {[a-zA-Z0-9]} $c]} {
should be changed to
if {![string match {[-a-zA-Z0-9~._]} $c]} {
unless there is some character set difficulty unknown
to me.
