Can't include hyphenated names in Spanish personal word list about dict HOT 3 OPEN

You need to update the es.dat file to allow dashes in the middle of words. Without checking, something like:
special - -*-
Which means "Allow the special character "dash" to appear in the middle of a word but not at the beginning or end."

The incantation that will take care of both problems GNUAspell/aspell#551 and GNUAspell/aspell#552 and I could not find any metioning of it on any documentation is:

special - -*- ' -*-

One question remains: Since both occurrences are common in Spanish, how come this is not standard in the files es.dat?
