  I can do better: I can verify it's Not A Bug by running the script on cygwin
and seeing that it works fine.  On the other hand, if I get the script to run
"unix2dos" on 'expressions.txt' and 'text.txt' before grepping them, I get the
result you were expecting.  

  Are you on a textmode mount or something?  Or do you perhaps have some dos
line-endings in the grepbug script file itself?


    cheers,
