draw is the function which update the Xwindow with the information st has,
and it is designed in a way that it must be called once in the main loop
(run function), and calling it in other places it is a waste of time.
The way st knows if there is a selection activated is checking if sel.ob.x
is equal to -1. In some parts of the code the way of disabling the selection
was only setting it to -1, but after it you can't be sure if the selection
is clearing from the terminal representation, because it is necessary mark
all the lines affected by the selection as dirty. Already there is a functon
which perform this task, selclear.
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.

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.
