After the recent discussion about error messages at startup (this time it was about pure-space-overflow) it came to my mind I often tend to miss errors at startup. You can not see them because of the splash screen for example. I just started testing `lwarn' because of this. I did something like this:

   (condition-case err
       (require 'something-bad)
      (lwarn '(.emacs) :error "%s" (error-message-string err))))

I wasn't aware of lwarn, so I checked it's doc string and found a
really minor error: the first period in the description of the
TYPE argument should either be deleted or replaced by a comma:

,----[ C-h f lwarn RET ]
| lwarn is an autoloaded Lisp function in `warnings'.
| Display a warning message made from (format MESSAGE ARGS...).
| Aside from generating the message with `format',
| this is equivalent to `display-warning'.
| TYPE is the warning type: either a custom group name (a symbol).
| or a list of symbols whose first element is a custom group name.
| (The rest of the symbols represent subcategories and
| can be whatever you like.)
| LEVEL should be either :debug, :warning, :error, or :emergency
| (but see `warning-minimum-level' and `warning-minimum-log-level').
| :emergency -- a problem that will seriously impair Emacs operation soon
|             if you do not attend to it promptly.
| :error     -- invalid data or circumstances.
| :warning   -- suspicious data or circumstances.
| :debug     -- info for debugging only.
