Comment(by raimue@…):

 `patch-macports-curl-escape.diff` is a patch to add a `curl escape`
 command, using curl_easy_escape() internally.

 {{{
 $ rlwrap /usr/bin/tclsh
 % source /Library/Tcl/macports1.0/macports_fastload.tcl
 0
 % package require Pextlib
 1.0
 % curl escape foo~bar+baz!
 foo%7Ebar%2Bbaz%21
 }}}
