ledger-complete-in-steps set to t causes problem with company-mode

[drdv]

Consider the following transaction:

; 
2025/01/06 * Cinema
    Expenses:Cinema                           €18.00
    Cash

With point after the initial comment, pressing space gives

Company: backend company-capf error "Not on a posting line" with args (candidates ;  )

This is when using:

(add-hook 'ledger-mode-hook
          (lambda ()
            (setq-local tab-always-indent 'complete)
            (setq-local completion-cycle-threshold t)
            (setq-local ledger-complete-in-steps t)))

The problem comes from (setq-local ledger-complete-in-steps t), which activates the use of ledger-complete-account-next-steps where we have:

(unless (eq 'posting (ledger-thing-at-point))
  (error "Not on a posting line"))

My guess is that using company-mode together with ledger-complete-in-steps set to t is not intended, but there are valid use cases.

If I simply remove the (error "Not on a posting line") things seem to work fine (the tests pass).
