TAGS are off by one line

[cheater]

in vim, when i use ctrl-] to jump to a tag, I am placed on the line preceding the thing I jumped to.

i created tags using hasktags -bx .

my vimrc looks like this:

set ignorecase
set hls
set smartcase
set hidden
set et
set sw=2
set tw=4
set incsearch
set paste

if !has("nvim")
    :set cryptmethod=blowfish
endif

set tags=./TAGS,TAGS
autocmd BufWritePost *.hs :silent! exec "!hasktags --etags ."
autocmd BufWritePre *.hs :%s/\s\+$//e

for example, I have a constructor called DoCapture that looks like this:

| DoCapture FeedCaptureMode FeedSource Bool (Maybe [ProductionId])

and the TAGS file says: | DoCapture ^?DoCapture^A85,86

where ^? and ^A are escape sequences.

forgot to add, DoCapture is on line 86
