zile: update to 2.6.2

2.6.1 -> 2.6.2:
- fixed opening a file that contained no line endings would cause a
  null pointer dereference.

2.6.0 -> 2.6.1
- Many bugs fixed due to the Vala rewrite.

2.4.15 -> 2.6.0
- Zile has been rewritten in Vala
- Writing files has been made more robust
- Fixed a bug where `save-buffers-kill-emacs' would not cause Zile to
  exit immediately if it was executed as part of a macro or Lisp
  expression.
- Fixed bug where `universal-argument' without an explicit numeric
  argument would cause Zile to quit immediately.
- Fix a space leak on unterminated string and a crash on unclosed paren when
  parsing Lisp expressions.
- In the minibuffer, C-k now adds the cut text to the kill ring, and `yank'
  (C-y) is added.
- Fix processing of key bindings. This affects where-is and
  describe-bindings.
