ledger-add-transaction candidate narrowing

[lcvass]

Hello!

I usually add a new transaction by interactively calling ledger-add-transaction, which prompts for a date and then prompts for a xact string. The string prompt has become a pain point as I have a ton of past payees in my file and it's really hard to guess what payee ledger will guess from a given string.

Is there any way to preview/narrow the existing payees in the minibuffer when using xact?

@lcvass This has bothered me quite a bit in the past, too. I decided to implement a live output preview rather than just narrowing or showing a list of payees, since the ledger xact command can also be used to input accounts and amounts. Would you mind giving #461 a look and providing some feedback on the experience?
