I haven't found a way to disable spell checking for single character "words", like when you type 100k (k as in thousand) and it gets highlighted as a mistake. I already tried this:
syn match SingleChar '/\<\S\>' contains=@NoSpell
But it doesn't do a thing.
I know I could add all characters in a spell file but that seems a bit cheap and would require me to move my spell file around with me instead of just the vimrc.
Thanks in advance!
