Summary: Search/Expand fails on 2nd set of [ & ]

Initial Comment:
Search followed by an expand or group() fails to select
any data from the string being searched when 

(a) the search pattern seeks a [ and ] in the string, and

(b) the string contains two pairs of [ and ].

I.e., if the search pattern is 

"\[spam.*\] *(.*)"

and then we search two strings:

str1 = "[spam score 10/10] Spammer Junk"

str2 = "[spam score 10/10] Spammer Junk  [spammer's token]"

we should match, and then be able to expand, the entire
remainder of the string excluding the opening [spam
score.*]. However, this only works for the first
string; the second string fails.

I regret to say that the resolution of this problem is
not obvious from the source file.
