[dev] [st] [patch] Remove redundant xtermclear code

[Ton van den Heuvel]

In case anything gets drawn in drawregion, xdrawglyphfontspecs ensures
that the region that needs to be drawn to is cleaned up. In case this
patch is not accepted; the current code contains an issue;

-        xtermclear(0, y, term.col, y);
+        xtermclear(0, y, term.col-1, y);
