Note that the use of "%20" (this is a blank) is forbidden
in query strings. In query strings, blank must be coded as "+".

I have problems to understand what you want...

  When you repeat the ids separately, the URL will become longer...

  Repeating separately would look like:

	tal:define="
	  ...
	  ids result/CourseLike;
	  repeatedIds python:'&'.join(['id:list=%s' % id for id in ids]);
	  ...
	  "
	  >...
	    tal:attributes="href string:detail_html?$ids"

The code above assumes that "result/CourseLike" returns a
sequence of ids. If instead it returns a string, it will
need to be split at its element separator (apparently ", ") to
obtain a list of ids.
