vt: selection: take screen contents from uniscr if available

Browse source

This preserves whatever was written even if we can't currently display the
given glyph.  Mouse paste won't corrupt any character of wcwidth() == 1
anymore.

Note that for now uniscr doesn't get allocated until something reads
/dev/vcsuN for that console, making this code dormant for most users.
