" 例如:set ffs=unix, dos ff=unix则预设为unix格式，但如读入的是dos格式的
" 档案，会自动调整为dos格式，这样存档时就会以dos格式存档。设置即为:
" set fileformats=unix
" set fileformat=unix并不会依据载入的档案形式来调整ff，并且只用unix形式
" 所以，可以解决windows下的^M问题。
" :set ff 可以查看当前文件fileformat
" :set ffs 查看vim设置
" 其实fileformats可以这样调整
" set fileformats=unix,dos       这样也应该是可以解决^M问题的，让vim自动
" 去选择是用dos，还是unix的，这应该是vim的默认设置，
" 当然也可以选择全局替换:%s/^M//g
