If I've worked out correctly what you're trying to do (exclude files
which have the same basename as a .tex file), how about something like
this...


vim-files() {
  local dir
  if [[ $PREFIX = */* ]]; then
    if [[ $PREFIX[-1] = / ]]; then
      dir=$PREFIX[1,-2]
    else
      dir=${PREFIX:h}
    fi
  else
    dir=.
  fi
  local -a texfiles nontexfiles
  local -aU suffixes
  texfiles=($dir/*.tex(N))
  if (( $#texfiles )); then
    notexfiles=(${texfiles:r}.*)
    suffixes=(${${notexfiles:e}:#tex})
    reply=("^*.(${(j.|.)suffixes})")
  fi
}
zstyle -e ':completion:*:*:vim:*' file-patterns vim-files
