* Remember original postings during infer and pivot
This includes such functions like:
- inferFromAssignment
- inferBalancingAmount
- inferBalancingPrices
- pivotPosting
* Use original postings for hledger print
- Introduce "--explicit" option for "print" command which brings back
old behavior when every inferred number being printed.
- Make "print" by default print original postings without inferred
amounts. But use effective account name to have effect from aliases.
- Instruct shell tests with an new expected output or to use
--explicit option when inferred amounts are checked.
Resolvessimonmichael/hledger#442
* Changed behavior of `readJournalFiles` to be identical to `readJournalFile` for singleton lists
* Balance Assertions have to be simple Amounts
* Add 'isAssignment' and 'assignmentPostings' to Hledger.Data.Posting and Transaction
* Implemented 'balanceTransactionUpdate', a more general version of 'balanceTransaction' that takes an update function
* Fixed test cases.
* Implemented balance assignment ("resetting a balance")
* Add assertions to show function
* updated the comments
* numbering is not needed in journalCheckBalanceAssertions
* remove prices before balance checks
* rename functions
print now always right-aligns the amounts in an entry, even when they
are wider than 12 characters.
If there is a price, it's considered part of the amount for
right-alignment. Maybe it would be nicer to put amounts and prices in
separate columns ? That will get a little complicated, needs more
discussion/design.
Also some cleanup of postingAsLines.
