Devhelp development notes
Refactorings - misc notes
DhWindow: move code outside of new(), move it in init() for example.
DhWindow: copy_cb() doesn't seem at the right place.
- Parser: is the Devhelp index file format version 2 documented?
- Parser: write basic unit test.
Use GtkGrid wherever possible, not GtkBox (will ease the port to GTK+ 4).
- See also FIXME/TODO/XXX comments in the code.
