Subject: [PATCH 0/3] use unicode for vt mouse paste

Hi!
Based on Nicolas' nice work (in tty-next), let's avoid corrupting characters
that have been copy+pasted via mouse selection.  The uniscr array holds
their original identity even if they got mangled by glyph conversion.
The glyph conversion lossily turns similar-looking characters into a
representation, and everyone else into a replacement character.

There's no proper handling for CJK (yet?) but anything of wcwidth()==1 will
work fine.

The whole thing doesn't get enabled until something reads from /dev/vcsu for
that console, but let's test this code first before enabling it widely.
