[Vala] Emendo text editor

[simargl <archpup gmail com>]

Hi,

Emendo is a simple text editor with syntax highlighting written in Vala,
using Gtk+3 and Gtksourceview. If someone is interested source tarball can
be found here:http://alphaos.tuxfamily.org/forum/viewtopic.php?f=8&t=702#p1151

Presenting this text editor to you is one thing, but more important there
are two known bugs I am still not able to solve:

First, before closing program from toolbar or with Ctrl+Q, there is
source_buffer_check method called (line 700) from action_quit (line 573)
method, that offers to save changes if source buffer is modified. That
works fine if program is closing from toolbar button or Ctrl+Q, but when X
in titlebar is clicked, program first closes then shows that dialog box and
offers to save changes.

Second, replace_all method (line 545) works OK, but it is not undoable,
when undo button from toolbar is clicked, everything from sourcebuffer gets
deleted.

Thank you for any help.
