Case-sensitive-search

[Jan Walker <JWALKER at SCRC-TENEX>]

       Where's "fs bothcase"?
    Gee, where'd you pick that one from?  It's a TECO "FS flag".  It controls whether
    searches are case-sensitive or not.  Has this anachronism made it into ZWEI?
Come on.  Of course I know it's a teco flag.  I was taking a short cut
by using the quotes.  What I should have said was "Where's the ZWEI
analog of fs bothcase?  I need case-sensitive searches."  Sorry.  But I
guess I have my answer: "There isn't any".  Right?
