<p>Bash allows more characters besides <code>[[:alnum:]_]</code> when declaring<br>
function names using the <code>function</code> keyword.  It also does not require<br>
having a pair of parentheses after the name.  Some shells may actually<br>
implement it differently but we don't have to be that strict since the<br>
user explicitly specifies the <code>function</code> keyword anyway.</p>

<p>This update implements the one described above, and also invalidates<br>
function names that are completely made up of digits.</p>
