Builtin commands are now gathered more tightly in a single module,
Hledger.Cli.Commands, reducing duplication and facilitating change.
The tests command was difficult and has been dropped for now.
The obsolete convert/info/man commands have been dropped.
cli: refactor: a proper commands list, better Main/Commands separation
The legacy "convert" command has been dropped.
The activity command's module is now named consistently.
I dropped these last month, perhaps without meaning to.
They probably should stay. hledger-ui (eg) will still build
with minor updates of hledger-lib or hledger, but will require
either a release or a hackage revision to build with a major
update.
Older megaparsec is still supported.
Also cleans up our custom parser types,
and some text (un)packing is done in different places
(possible performance impact).
When the transaction list changes, eg due to toggling a query filter,
and the previously selected item has disappeared, instead of moving
the selection to the end, we now select the nearest transaction by
date (and if several have the same date, by journal order).
In the accounts and register screens:, you can now scroll down further
so that the last item need not always be shown at the bottom of the screen.
Also we now try to center the selected item in the following situations:
- after moving to the end with Page down/End
- after toggling filters (status, real, historical..)
- on pressing the control-l key (should force a screen redraw, also)
- on entering the register screen from the accounts screen (there's a
known problem with this: it doesn't work the first time).
Items near the top of the list can't be centered, as we don't scroll
higher than the top of the list.
