[GiNaC-list] Some static functions

[Chris.Dams at mi.infn.it]

Dear Martin,

> collect_symbols and get_symbol_stats are mentioned in the manual,

Are they? Doing "grep collect_symbols ginac.texi" or "grep
get_symbol_stats ginac.texi" does not give any result.

We cannot add them in the 1.3 branch since that should be binary
compatible. I suggest you copy the code from normal.cpp. I guess these
functions were not thought to be very useful for users.

Best wishes,
Chris
