Adam Kruszewski 446f88ff78 Fixed error when no further candidate was found ... When corfu--candidate was ended up as nil, the overlay still held previous value but was not updated as the error was raised in the update function. Additionally when the backend is not keeping up we use the previous candidate to update what the user see using all of the information we had (i.e. prefix and the candidate), so we borrow a character from one and append/prepend to the other when necessary. This gives a little better experience when using slow backend such as lsp.		2023-05-07 17:06:36 +02:00
