tests: use "?" to glob both ":" and ";" in output for test portability If environment variable looks like PATH or so (e.g. any of components joined by ":" contains "/"), ":" in it is replaced with ";" by MinGW at spawning Windows native process, to follow path concatenation style of Windows. Therefore, "bundle:../full.hg" is converted into "bundle;..\full.hg" on MinGW. Difference between "/" and "\" is automatically ignored by "(glob)", but difference between ":" and ";" should be globed explicitly.
