How can I change vim's spell checking, so that it does not mark words with capital letters, which were previously unknown to vim, but were added to a custom dictionary in lower case form, at the beginning of a phrase, where they suddenly have a capital letter as first letter, as wrong in general?I know it does this for known words already, but I added a custom word:lern-didaktischeI added it using the visual mode and selecting the whole word and then pressing zg to my custom file ~/.vim/spell/custom.utf-8.add.In the next phrase there is the same word, but at the beginning of the phrase:Lern-didaktischePhrases are separated by . and a space  in my document. Although the non-capitalized version is already known to vim and not marked as wrong anymore, this one is still marked as wrong. To be precise, the first part before the - is marked as wrong. However, I cannot simply add it like the other version of the word, because I don't want to allow it to have capital L where ever it stands. The capitalized version should only be correct at the beginning of phrases, because it is an adjective and we don't give adjectives a capital letter at the beginning, except at the beginning of a phrase.Return value of :verbose set spellcapcheck:spellcapcheck=[.?!]\_[\])'^I ]\+
