You have indeed found an oops! in the published regex, but the fix is not as
drastic as you suggest.
Each lin in the regex is intended to make one of the fields required, the first
field in the regex. It presumes all preceding fields are missing (or a
preceding line would be matched), and it makes all following fields optional.
Thus, one of the six lines should match starting with the first actually
present field. Each first-in-the-line field of the regex should be required,
i.e., not followed by a question mark. There are two lines in which a spurious
question mark on the first field is present and must be removed: the line
beginning '|([0-9]+D)?' should have that question mark removed; similarly for
the line beginning '|([0-9]+M)?'. @%#%& cut-and-paste errors.
Sigh. You can't imagine how many times that regex has been checked. :-(
