* Remove 'col' from linters where it is hardcoded to 1 When 'col' is 1, the first column will get highlighted for no reason. It should be 0 (which is the default). In the scalac linter there was also a check about the outcome of `stridx`. It would set l:col to 0 if it was -1, and then it uses `'col': l:col + 1` to convert the outcome of `stridx` to the actual column number. This will make 'col' equals 1 when there is no match. We can remove the check because `-1 + 1 = 0`. * Remove outdated comments about vcol vcol was added as a default, and the loclists that follow these comments do not contain 'vcol' anymore Conflicts: ale_linters/elixir/dogma.vim
