mpq_class documentation is not explicit about canonicalization

[gsauthof at techfak.uni-bielefeld.de]

Hi,

the paragraph about the mpq_class(integer num, integer den) constructor
does not state if the rational num/den needs to be in canonical form.
[1]

Please add a sentence, which clarifies the description.

Best regards
Georg

PS: Btw, prefixing the constructor name with 'void' gives the wrong
impression that this is valid C++ syntax and/or that constuctors may
have return values ...
