[fpc-pascal] A bug in documentation?

[Vladimir Zhirov]

Hi,

Language Reference, Section 1.4 Identifiers says:

> Identifiers consist of between 1 and 127 significant characters
> (letters, digits and the underscore character), of which the
> first must be an alphanumeric character, or an underscore (_).

Should "alphanumeric" be "alphabetic" here? Since
alphanumeric = alphabetic + numeric it looks like
starting an identifier with a number is valid,
but it is not.
