Function ns-file-name makes incorrect call to clojure.string/replace when File/separator is "\\" (e.g. Windows)
On Windows, where File/separator is a string consisting of a single backslash character:
I'd recommend using str/replace calls like the first one above when the things you want to replace are constant strings.
In release 0.2.6
Patch tns-22-v1.patch changes the only 2 calls to clojure.string/replace I found in tools.namespace that could have their second arg be a constant string rather than a regex.
