If I load a csv file and want to change the filetype to disable the csv features by setting :set ft=txt or somethin similar, I get many error on using h, j ,k , l and the cursor keys for movement that make it impossible to work unti the filetype is set back to csv.
Error for h, j, k and l keys are only shown if g:csv_highlight_column is enabled, because the HiColumn function isn't available anymore but already referenced throuhgt autocommand for CursorMoved.
Maybe we should have a second function to cleanup all staff done by InitCSV.
Pretty nice, no more errors. But I got a message on startup that the command HiColumn is not defined. I haven't tested it much, but this patch should remove the warning on startup (fanglingsu@55c69f9).
Thanks, included it and pushed it to master
