In egrep (grep 3.0), the order of options (multiple --include and --exclude), is surprisingly significant.

I was puzzled by 5 extra output lines in my first egrep,

so I did another egrep, with the --include moved up front.

Known bug?

Yes, I realize that the include by itself would have been sufficient, the exclude in this case is superfluous.

Thx,

John R.

That's expected behavior, but it's not documented and should be. Thanks for bringing it up. I installed the attached doc patch.
