Subject: There is no need to clear every line entirely before drawing to it,
 this means moving the cursor and messes up wrapping. Better to just clear the
 sections that aren't written over. GitHub issue 2537.

Subject: Send Unicode directional isolate characters around horizontal pane
 borders if the terminal support UTF-8 and an extension terminfo(5) capability
 "Bidi" is present. On terminals with BiDi support (ie, VTE) this seems to be
 enough to display right-to-left text acceptably enough to be usable (with
 some caveats about the mouse position). Requested by and with help from
 Mahmoud Elagdar in GitHub issue 2425.
