-   identifiers can use all sorts of characters that no assembler would
-   tolerate, so the alphabet this function creates is a little odd.
-   Here are some sample mangled identifiers offered by HP:

-	typeid*__XT24AddressIndExpClassMember_

-   this is right, but I still strongly suspect that there's a
-   misunderstanding here.
-
-   If we decide it's better for c++filt to use HP's assembler syntax
-   to scrape identifiers out of its input, here's the definition of
-   the symbol name syntax from the HP assembler manual:
-
-       Symbols are composed of uppercase and lowercase letters, decimal
-       digits, dollar symbol, period (.), ampersand (&), pound sign(#) and
-       underscore (_). A symbol can begin with a letter, digit underscore or
-       dollar sign. If a symbol begins with a digit, it must contain a
-       non-digit character.
