I do not like the idea of a list of separators...
but we may add an "int (*) (int)" argument :-P
This way the user can specify the preferred "isspace" function! :-D

To be honest, the GMP manual is not completely correct.
Whitespace is not allowed immediately after the minus "-" sign; nor,
when base = 0, in the middle of the base prefix: "0x", "0X", "0b", "0B"
can not be "0 x", ...
Would you suggest to document the two exceptions, or to change the code
for a strict ignore-everywhere policy?
