This introduces some new helper functions which are exactly the same
as what we had before, but do not call
normaliseMixedAmountSquashPricesForDisplay, so that we can use the new
functions for displaying Transaction and Posting. It also goes through
and gets rid of most uses of the old showMixed* functions which would
benefit from using the new interface.
As a consequence of fixing #457, two rewrite tests fail, because extra
quotes appear in the output of the commands being tested.
These quotes appear in comments which reflect the command which was
run in order to produce the output. Instead of
; generated-posting: = assets:bank and amt:<0
we now get
; generated-posting: = assets:bank and "amt:<0"
Given that the quotes around `amt:<0` are necessary for the command to
work properly, these quotes should really be there in the expected
output.
Hence this commit modifies the expected output of the tests, by adding
in the quotes. This makes the tests pass once more.
