Bug 10601 – std.path.setExtension leaves trailing dot if extension is empty

Code: -----snip----- import std.path, std.stdio; void main() { version(Windows) string ext = ".exe"; version(Posix) string ext = ""; string srcfile = "program.d"; writeln(setExtension(srcfile, ext)); } -----snip----- Output on Posix is "program." (with the stray trailing dot). When an empty extension is given, setExtension should simply strip the extension.

If extension is empty, std.path.setExtension should be equivalent to std.path.stripExtension. This special case is useful in generic code that needs to alternate between, e.g., .exe on Windows and no executable extension on Posix. https://github.com/D-Programming-Language/phobos/commit/f2bd29cb97033ae041ebfd32690f01ddb25b98b7 Merge pull request #1409 from quickfur/issue10601 Fix issue 10601.
