We're now clearing empty areas with spaces, so there is no point to check
if character contains non-empty string.

The commit b78c5085f7 changed the st behaviour enabling BCE capability,
that means erase regions using background color. Problem comes when you
clear a region with a selection, because in this case the real mode of the
Glyph is not the value of term.line[y][x], due in drawregion we had enabled
the ATTR_REVERSE bit.

Now double-click+dragging automatically snaps both ends to word boundaries
(unless on series of spaces), and triple-click selects whole lines.
As a side effect, snapping now occurs on button press, not button release
like it previously was, but I hope that won't be inconvenient for anyone.

Now, when you are selecting a region, you will get all empty lines that happen
to be in it, including trailing ones. Last line terminator is omitted as it previously
was, though.

Now, newly allocated Glyphs are set to spaces and current cursor colors
with tclearregion() routine.

To have a more visible cursor on unfocused windows this patch makes st draw a
rectangle around the terminal cell.

Thanks Mark Hills <mark@xwax.org> for the suggestion!

The copying and pasting in the terminald and GUI world is flawed. Due to the
discussion on the mailinglist it seems that sending '\n' is what GUIs expect
and '\r' what terminal applications want. St now implements that behaviour.

People sending me patches against strange revisions and basing on their own
revisions make me having to reapply them. Then such errors appear.
