Binary files are not moved

[dkrikun]

If --text-only is not specified, and lets say, we have a folder C:\my\xyz\builds with 2 files: xyz.vcproj and xyz.exe, running rename.py xyz abc * from within the folder will create C:\my\abc\builds\abc.vcproj but leave C:\my\xyz\builds\xyz.exe because it's binary. This is somewhat surprising.
