gtk_entry_set_text() patch review

[Matthew Barnes <mbarnes redhat com>]

There's a trivial patch in bug #58777 to make gtk_entry_set_text() treat
NULL strings the same as zero-length strings.

https://bugzilla.gnome.org/show_bug.cgi?id=58777

Can we get this in please?  Rejecting NULL strings with a runtime
warning just makes it unnecessarily difficult to bind GtkEntry:text to
other string properties.  gtk_label_set_text() already gets this right.
