[bug#49482] [PATCH 3/3] ci: Properly construct URLs.

[Hartmut Goebel]

Hi Mathieu,
thanks for the review. I updated the doc-string, fixed the other parts 
and pushed as 3ee0f170c8bd883728d8abb2c2e00f445c13f17d.

False is used to omit elements from the query-string.

Booleans and other types are not handled, since this low-level function 
doesn't know how to convert them into a string to be put into the query. 
#t could be "1", "t", "true", depending on the API used.
