[ale] hmm. yer never too old to trip on Grep Reg Expressions

[neal at mnopltd.com (Neal Rhodes)]

So, I need to look in about a bazillion source files for variants of

        DEFINE BUFFER SNORT FOR ALTPLAN.
        Define Buffer Blech for AltPlan.
        Def    Buff   Blurf for AltPlan.
        Def Buff Blurf for AltPlan.
        def buff blurf for altplan.
        define buff blurf for altplan.
        define                      buffer                   blorf for
        altplan.
        define  new shared buffer                   blorf for altplan.
        

And grap 3 lines before, 10 lines afterwards, source file and  line#. 

I was thinking this would to it: 

        grep -i -B 3 -A 10 -H -n -r -f buf-grep.inp * > buf.grep.out
        

Where buf-grep.inp was


        def*buff*for*ALTPLAN
        
        def*buff*for*ARM
        
        def*buff*for*ARMNOTE
        

Alas it is not thus, and the more I study the reg exp notes the more I
see there error of my ways, and the less I see an expression that would
work.
