Remove redundant spaces from return types and default values/types.

Browse Source 
Doxygen generates extra spaces in some function return types (e.g. involving
a const reference) and template parameter defaults (in partucular, when
the default is formatted across multiple lines in the C++ source).
Normalize spaces in those cases.
