Subject: [PATCH] Fix a bug introduced in r32678

string.gsub returns 2 values, the new string and the number of
replacements made. It also has a 4th argument, the number of
replacements to make. So when you use the return value of gsub as the
3rd argument, and no replacements were made, it instructs the next call
to not make any replacements. Thanks to Ron Bowes for reporting this
issue.
