[PATCH xrandr] Print spaces between XA_ATOM property values

[Aaron Plattner]

Commit b26fd532b3dab222956ea27eef4e41345978b5b2 redid how xrandr prints
properties.  It neglected to put spaces between the values of XA_ATOM
properties, so they all run together.  For example,

    audio: auto
        supported: force-dvioffautoon

Fix this by putting a space after each atom name.  In addition, some drivers
create property values with spaces in them, so put commas between entries to
disambiguate.  For example,

    Broadcast RGB: Automatic
        supported: Automatic, Full, Limited 16:235

Do the same for properties with multiple valid ranges.
