This is GNU diff 2.0, installed with GNU C 1.41 under COFF encapsulation on a 386/ix 2.0.2 system, waiting for Hurd :-). The command `diff - -' exits right away with status 0 without reading standard input at all. By contrast, `diff - /dev/null' reads standard input until end of file. It is not clear from the documentation what `diff - -' really means. I would suggest that this particular case be caught and diagnosed as improper usage, and be also documented as such. -- Franc,ois Pinard ``Happy GNU Year!'' pinard@iro.umontreal.ca (514) 588-4656 ...!uunet!iros1!pinard About the League for Programming Freedom?
