massageExponent()

Be consistent about leading 0 in exponent.

POSIX specifies that e (hence g when using it) uses at least two digits in the exponent, requiring a leading 0 on single-digit exponents; (at least) MinGW includes a leading zero also on an already-two-digit exponent, e.g. 9e-040, which differs from more usual platforms. So massage that away.
