bug#17927: 24.3.92; Warnings for init file are not visible after loading the desktop

[Juri Linkov]

Version: 24.3.92

> When an error occurs while loading the init file, the
> *Warnings* buffer is displayed but hidden immediately
> when the desktop restores the previous window configuration
> by running `desktop-read' from `after-init-hook'.
>
> A possible solution is to postpone displaying the
> *Warnings* buffer to the end of `after-init-hook':

Fixed in the emacs-24 branch since it's a regression.
