Compilers such as gcc and clang seem to perform this rewrite automatically when the lookup string is known at compile-time to contain a single character. The MSVC compiler does not seem apply the same optimization, and the code being adjusted here is within an #ifdef WIN32, so it seems worth adjusting this with the assumption that strchr() will be slightly more performant. There are a couple more instances in contrib/fuzzystrmatch that this commit could also have adjusted. After some discussion, we deemed those not important enough to bother with.
