Add account partial completion and keyword, commodity completion

[a-bali]

Would it be possible to implement:

1. Partial completion for account fragments a la vim-beancount, where e.g. InInBo completes to Income:Interest:Bond
2. Completion for commodities, e.g. 2024-01-01 price MSF<TAB> to 2024-01-01 price MSFT (MSFT being the commodity)
3. Completion for keywords, e.g. 2024-01-01 pr<TAB> to 2024-01-01 price (price being the keyword)

will look into 1 and 2
3 should be in the latest release

I don't seem to have point 3 in 1.3.4 (only for open/close/balance/txn), is it possible that I'm missing something?

1. (InInBo -> Income:Interest:Bond) works for me in 1.3.3, but not in 1.3.4
