Vagrant.bat file should look like this...

Please merge this...
- I changed REM directives to much nicer "::" format (valid from day one in DOS)
- fixed two typo bugs that I raised issues (but they are still unresolved after two months)
- I fixed a problem when user interrupted .bat file execution. In the past, that was big problem - has been leaving current session's environment in a mess.

With this fix concerning environment variables, you can execute normal Ruby and Vagrant, in the same shell, at the same time, without messing each other.

So please, take look at this and merge it.
Please. Not two months...
