} The only way I can get it to work is if I do an initial ^X^X after typing 
} the prefix.  If I do <CR>fred<UP> then it just scans through the history 
} matching on nothing at all.

Hrm.  I get the behavior Christopher describes with 3.0.0 and 3.0.1; but
it stops for me as of 3.0.3 (I don't have a 3.0.2 around to try), and I
don't see it in 3.0.4 or 3.0.5.

I believe this ChangeLog entry is relevant:

        * Src/zle_utils.c: move the mark when characters are
          inserted/deleted.  From Peter (2807)

} BTW, it was not very easy to compile on the Dec Alpha under OSF/1 
} version 3.2.  In Src/Zle/zle_tricky.c line 1551 the parameters to
} yp_all() are not the same (the third parameter is the callback structure
} on OSF1, not a pointer to it as in the code.

Actually, it's the parameter in the prototype in the header that is wrong,
not the pointer in the zsh code.  There's a discussion of this somewhere
in Etc/MACHINES.
