 DESCRIPTION
 
-	Return 0 if no conversion is performed, 1 if a string is converted.
+	Assume that *type points at a count in a mangled name; set
+	*count to its value, and set *type to the next character after
+	the count.  There are some weird rules in effect here.
+
+	If *type does not point at a string of digits, return zero.
+
+	If *type points at a string of digits followed by an
+	underscore, set *count to their value as an integer, advance
+	*type to point *after the underscore, and return 1.
+
+	If *type points at a string of digits not followed by an
+	underscore, consume only the first digit.  Set *count to its
+	value as an integer, leave *type pointing after that digit,
+	and return 1.
+
+        The excuse for this odd behavior: in the ARM and HP demangling
+        styles, a type can be followed by a repeat count of the form
+        `Nxy', where:
+
+        `x' is a single digit specifying how many additional copies
+            of the type to append to the argument list, and
+
+        `y' is one or more digits, specifying the zero-based index of
+            the first repeated argument in the list.  Yes, as you're
+            unmangling the name you can figure this out yourself, but
+            it's there anyway.
+
+        So, for example, in `bar__3fooFPiN51', the first argument is a
+        pointer to an integer (`Pi'), and then the next five arguments
+        are the same (`N5'), and the first repeat is the function's
+        second argument (`1').

+   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:

+   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.
