A transaction/posting status of ! (pending) was effectively equivalent
to * (cleared). Now it's a separate state, not matched by --cleared.
The new Ledger-compatible --pending flag matches it, and so does
--uncleared. The equivalent search queries are now status:*, status:!
and status: (the old status:1 and status:0 spellings are deprecated).
Since we interpret --uncleared and status: as "any state except cleared",
it's not currently possible to match things which are neither cleared
nor pending.
The regex account aliases added in 0.24 trip up people switching between
hledger and Ledger. (Also they are currently slow).
This change makes the old non-regex aliases the default; they are
unsurprising, useful, and pretty close in functionality to Ledger's.
The new regex aliases are also available; they must be enclosed in
forward slashes. Ledger effectively ignores these, which is ok.
Also clarify docs, refactor, and use the same parser for alias
directives and alias options
-N doesn't seem to be used by Ledger currently; we'll
use it as shortcut for --no-total.
-T is used by Ledger to set a custom value expression for the final
total. I'm going to take it as a shortcut for --row-total instead.
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).
