commit 713a4bc48c52058172520805373103c79ef17a3a (HEAD)

    doc: replace characters for (R) symbol in Linux guide

    [ upstream commit c265d58619e7fc0f72441faafec56a2a8633a15b ]

    Some IDEs, such as eclipse, complained on save about the use of special
    characters in the (R) symbol in linux GSG doc. We can replace those with
    the equivalent "|reg|" text, and including isonum.txt.
