Searching for prices during valuation no longer now properly excludes
price loops, avoiding near infinite looping with certain
configurations of market prices. Also we now always use a direct price
when available, rather than searching unnecessarily.
Price searching progress info, useful for troubleshooting, is now
displayed with --debug=2.
There could still be some corner cases we don't handle correctly. We
now give up with an error message if the searched price chains get too
long (> 1000). More importantly, we should also give up if the search
iterates too many times, but this is not done yet.
When generating a new posting as a multiple of an existing posting,
support conversion to a different commodity. For example, postings in
hours can be used to generate postings in USD.
Automatic transactions generated from rewrite rules use the commodity,
amount style, and transaction price if the rewrite defines a commodity.
This allows period and comma to be used for decimal point and digit group
separator or vice versa, and also flexible digit groups. See
http://en.wikipedia.org/wiki/Decimal_separator . Digit group separators
are possibly not worth the trouble and might not stay.
