Stripped down environment for new minttys created with Alt+F2

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a mintty instance
2. Use the system menu "New" option or Alt+F2 to open a new mintty instance
3. From the second instance, control+click on a file name

What is the expected output? What do you see instead?
The environment for the process launched when control+clicking on the file name 
from the second mintty instance only contains the environment variables PATH, 
SYSTEMDRIVE, SYSTEMROOT, and WINDIR. It is missing many important variables 
such as HOMDRIVE, HOMEPATH, USERNAME, APPDATA, etc...

In contrast, these environment variables are all present in the process 
launched when control+clicking on a file name from a directly executed mintty 
instance.

What versions of mintty, Cygwin/MSYS, and Windows are you using?
$ mintty --version
mintty 1.1.2

I had associated .c/.h files with a wrapper script I was experimenting with 
which would invoke gvim with different parameters depending on where the file 
was located based on a user configuration file located in the user's home 
directory. I noticed that my wrapper script sometimes didn't seem to be working 
and when debugging it I realized it was sometimes getting called without the 
environment variables needed for python to find the user's home directory. 
After some experimenting I found that this was only occurring in mintty's 
created with Alt+F2.
