except for several unused parameter warnings (because there is so much code
still #if 0'd out), and one implicit conversion from long long to long which
still has to be dealt with.
double has been disabled, because I am no longer packaging the gdtoa library
with Ledger (because double conversion really has nothing to do with what
Ledger does). If you wish to use it, you can find gdtoa in cpp-rewrite-2006,
under a sub-directory of the same name.
Complete changed the way format strings are handled. They are now
compiled first, which is far more efficient than what was being done
before.
Also, there is now a global ledger::commodity_t::commodities map,
which saves me from having to pass the current journal around to a
zillion different functions, for the sole purpose of making sure that
all commodity symbols that are parsed refer to the same commodity
object.
