Info-search searches the text on plain unfontified Info files (sometimes
fontification remains on parts of the Info file with visited nodes where
fontification was done, but search should work for general case with
unfontified Info files) and when it finds it narrows the Info file buffer
to the found node and calls `Info-fontify' on that node.

Fontifying the whole Info file before starting the search only for the
sake of putting text properties to help Info-search to find the text
that will be invisible after fontification is too costly operation.

Info-search should anticipate what text will be invisible (or will be
replaced by the `display' property).  To do this it should use rules
similar to rules used by `Info-fontify' and skip the text that
`Info-fontify' will make invisible.
