Completion seems to work ok overall (so
<C-]> complete for tags and
<C-P> complete in context), but the line completion (
<C-L>) always tells me "Pattern not found".
It does not work even when at the beginning of a new line (when
<C-L> should just copy the previous line).
Even when starting vim without anything (
vim -u NONE) line completion still does not work. huh?
