Back in the far-off twentieth century, it was normal on unix workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027 APOSTROPHE to be drawn as "’". This led to the convention of using them as poor-man's ‛smart quotes’ in ASCII-only text. However, "'" is now universally drawn as a vertical line, and "`" at a 45-degree angle, making them an `odd couple' when used together. Unfortunately, there are lots of very old strings in glib, and also lots of new strings in which people have kept up the old tradition, perhaps entirely unaware that it used to not look stupid. Fix this by just using 'dumb quotes' everywhere. https://bugzilla.gnome.org/show_bug.cgi?id=700746

* of the parent class.

|
|
* needed.
|
|
* @notify: the class closure for the notify signal
|
|
* @constructed: the @constructed function is called by g_object_new() as the
|
|
* final step of the object creation process. At the point of the call, all
|
|
* construction properties have been set on the object. The purpose of this
|
|
* call is to allow for object initialisation steps that can only be performed
|
|
* after construction properties have been set. @constructed implementors

|
|
* to complete its initialisation.
