      Vim's filename suffix to filetype translation is performed by the
      script $VIMRUNTIME/filetype.vim. The version of that file shipped
      with vim-6.2 includes these lines:

      " Fortran
      au BufNewFile,BufRead *.f,*.F,*.for,*.fpp,*.ftn,*.f77,*.f90,*.f95 setf fortran

      As you can see, the F90 suffix is not in the list. The proper way
      to fix this is to create your own ~/.vim/filetype.vim (for Unix)
      script and edit it to contain these lines:

      if exists("did_load_filetypes")
      augroup filetypedetect
      au! BufRead,BufNewFile *.F90 setfiletype fortran
      augroup END

      as shown under

      :help new-filetype

      You were confusing file types with file name suffixes. The correct
      syntax for an autocommand that makes those settings for fortran
      files is either

      autocmd FileType fortran setlocal formatoptions=croql cindent et comments=sr:!


      au BufNewFile,BufRead *.f,*.F,*.for,*.fpp,*.ftn,*.f77,*.f90,*.F90,*.f95 setlocal formatoptions=croql cindent et comments=sr:!

      Note the use of "setlocal" instead of "set" so that the settings
      apply locally to just that buffer instead of globally to every
      buffer. But if you're happy with vim's settings for .f90 files and
      you fix your filetype detection as described above, you shouldn't
      need either of those. If you decide you do want to change some
      setting for fortran files only, you should consider putting the
      commands in a file,
