} This is from the debian bug list:
} 
}   % a=abcd
}   % echo $a[1,(r)d]
} 
} didn't work, because it stopped one character too early trying to find
} the matching substring for `d'.

Note the (r) is forward pattern matching, not reverse; (R) is reverse.
Your patch appears to have fixed the bug only for the forward direction:

zagzig% x=abcd
zagzig% echo $x[(r)d]
d
zagzig% echo $x[1,(r)d]
abcd
zagzig% echo $x[(R)d]  
d
zagzig% echo $x[1,(R)d]

zagzig% echo $x[1,(R)c]
abc
zagzig%
