wm4 has already agreed on its redundant character. And as I have stated 
thousands of times, monow/monob shouldn't be used for palettized data. 
Just because a 1 bpp raw AVI file lacks a palette, it doesn't suddenly 
become monochrome. monow/monob is suitable for file formats with 
explicit black & white modes, like nut, TIFF and PNG. The BMP code does 
the right thing, it uses pal8 exclusively for 1 bpp.

Regarding "generation of invalid files", the only valid files FFmpeg 
will currently generate when using rawvideo is nut, regardless of using 
pal8 for 1 bpp raw AVI or not. The stride is incorrect for AVI and 
QuickTime files created with "-vcodec rawvideo", regardless of bit depth.
