ucfirst() new signature diagnostic messages

e.g.

    a slurpy parameter may not have a default value
=>
    A slurpy parameter may not have a default value

Also, split the "Too %s arguments for subroutine" diagnostic into
separate "too few" and "too many" entries in perldiag.

Based on suggestions by Father Chrysostomos.
