There is nothing wrong per-se, but this effort for aligning looks
amusing ;-) Perhaps the next person who wants to mimick this pattern
will order their constants in such a way that gives a shoter code to
a symbol with a longer name?

Did the order and additional blank line matter here? I think you'd
prefer to keep these two lines as before...

Other than that, the patch looks good.
Thanks.
