Accept the dot (`.') as the first character of an identifier. This may be
used for example to create macro names that start with a dot emulating
control directives of other assemblers. Note however, that none of the
reserved keywords built into the assembler, that starts with a dot, may be
overridden. When using this feature, you may also get into trouble if
later versions of the assembler define new keywords starting with a dot.
