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.
