Updated: mintty 2.7.9

[Thomas Wolff]

I have uploaded mintty 2.7.9 with the following changes:

Character display
   * Fixed character attribute handling in scrollback buffer.
   * Fixed rendering of some combining characters by heuristic tweaking.
   * Avoid misplaced artefacts of combining doubles while moving cursor 
over them.
   * Limiting glyph width checking to symbol ranges to avoid performance 
penalty (~#615).

Other
   * Unicode 10.0 updates.
   * Avoid multiple reporting of font problems.
   * Fixed process list in Close prompt (if started from desktop).
