4.2.3: mpf_set_str() no longer recognizes exponents with '+' prefix

[Jan Andres]

Hi,

Strings like "1e+3" are no more recognized by mpf_set_str() in 4.2.3,
only "1e3" is. This is a bit troublesome as on the other hand,
gmp_printf() and friends do output a '+'-prefixed exponent when using
the "%g" format. See below for proposed fix.

[OS, compiler info left out as this is a generic issue]
