The manual and hledger-web help says status values are *, ! or empty. Elsewhere the manual says they are 1 or 0.
status:X where X is anything but *, including !, seems to be parsed like status:(empty)
status:* in a hledger-web register view may be disrupting the running historical balance ?
tighten up status: docs and behaviour a bit (fix #227)
A status: query term no longer accepts * as a synonym for 1,
which was a bit confusing since 1 matches both * and !.
For now, it takes a value of 1 (true) or anything else (false).
