Hi.
There's a small improvement. When filling up the ChangeLog entries,
I see it handy to open a patch in a separate window. I would use
GCC_DIFF_FILE env. variable for saving of the diff file.

It seems easy enough to execute the command yourself in another window, 
but I'm not opposed to the change.

Maybe these environment variables should start with GCC_GIT, not just 
GCC, to give more indication what they're for.
