This commit introduces the commandline argument -%/--percent to show
percentages of the column's total instead of the absolute amounts for
each account in reports. The signs of the values are preserved.
This option is especially useful for the balance and incomestatement
commands.
If there are multiple commodities involved in a report hledger bails
with an error message. This can be avoided by using --cost. Also note
that if one uses -% with the balance command the chances are high that
all numbers are 0. This is due to the fact that by default balance sums
up to zero. If one wants to use -% in a meaningful way with balance one
has to add a query.
In order to keep the implementation as simple as possible --tree has no
influence over how the percentages are calculated, i.e., the percentages
always represent the fraction of the columns total. If one wants to know
the percentages relative to a parent account, one has to use a query to
narrow down the accounts.
Certain journal entries could trigger a bug where we displayed amounts
with the same character for digit group mark and decimal mark. Now if
a comma or period digit group mark is detected, that forces the
decimal mark to be the other character.
And if they did, the stats command would now throw an error.

fail is moving out of Monad and into it's own MonadFail class.
This will be enforced in GHC 8.8 (I think).
base-compat/base-compat-batteries 0.11.0 have adapted to this,
and are approaching stackage nightly
(https://github.com/commercialhaskell/stackage/issues/4802).
hledger is now ready to build with base-compat-batteries 0.11.0, once
all of our deps do (eg aeson). We are still compatible with the older
0.10.x and GHC 7.10.3 as well.
For now we are using both fails:
- new fail (from Control.Monad.Fail), used in our parsers, imported
via base-compat-batteries Control.Monad.Fail.Compat to work with
older GHC versions.
- old fail (from GHC.Base, exported by Prelude, Control.Monad,
Control.Monad.State.Strict, Prelude.Compat, ...), used in easytest's
Test, since I couldn't find their existing fail implementation to update.
To reduce (my) confusion, these are imported carefully, consistently,
and qualified everywhere as Fail.fail and Prelude.fail, with clashing
re-exports suppressed, like so:
import Prelude hiding (fail)
import qualified Prelude (fail)
import Control.Monad.State.Strict hiding (fail)
import "base-compat-batteries" Prelude.Compat hiding (fail)
import qualified "base-compat-batteries" Control.Monad.Fail.Compat as Fail
-V (and -X) now respects a report end date set with -e/-p/date: when
choosing the valuation date, similar to hledger 1.14 and Ledger.
This means that -V/-X aren't exactly like either --value=end or
--value=now. The "Effect of --value on reports" doc has been extended
accordingly, and much of it has been reworded and made more accurate.
dropped journalPrices
renamed Price to AmountPrice, AKA "transaction price"
renamed MarketPrice to PriceDirective.
added new MarketPrice (more pure form of PriceDirective without the amount style information)
Prices is now a more efficient data structure, but not used yet.
