Wouldn't it be better if the URL could be broken at an arbitrary position? That way, the length to cut could be made a function of some automatic fill factor, and wouldn't depend on where the URL happens to have some special break points.

As you know from the manual, an arbitrary position to break an URL is
given by @/.

It is hard-coded.

Users can use a particular version of texinfo.tex by placing the file
in the directory with the Texinfo source files.
