[O] bug#20090: 24.4: linking to a position within an info node

Is there an official format for the line numbers in Info cross-references?

(info "(texinfo) Printing Indices & Menus") documents the format of
line numbers only in the index, not in the cross-references:

   * In Info output, address@hidden' produces a special menu containing
     the line number of the entry, relative to the start of the node.
     Info readers can use this to go to the exact line of an entry, not
     just the containing node.  (Older Info readers will just go to the
     node.)  Here's an example:

          * First index entry:   Top.   (line  7)

     The actual number of spaces is variable, to right-justify the line
     number; it's been reduced here to make the line fit in the printed
     manual.

The Info reader already supports this format in the index.
