That is a completion which is aware of what it should complete.
Currently only account names are supported.
When you insert an account name like this:
Asse<C-X><C-O>
You will get a list of top-level accounts that start like this.
Go ahead and try something like:
As:Ban:Che<C-X><C-O>
When you have an account like this, 'Assets:Bank:Checking'
should show up.
This helps to avoid confusion when an account is not
seperated from the amount by two spaces or a tab but only by one space.
In these cases the amount will now be highlighted
as if it belongs to the account name.
Thanks to user 'plaindocs' for reporting this.
Also add option g:ledger_maxwidth to provide old behaviour
by putting a line like this in .vimrc:
let g:ledger_maxwidth = 80
I think that it would make sense to put all the functions and
everything that has to do with foldtext in ftplugin/ledger.vim
