Documentation:
Normal hook run after loading init files and handling the command line.
This is very similar to `emacs-startup-hook'. The only difference
is that this hook runs after frame parameters have been set up in
response to any settings from your init file. Unless this matters
to you, use `emacs-startup-hook' instead. (The name of this hook
is due to historical reasons, and does not reflect its purpose very well.)
