Feature request

[Łukasz Wieczorek <wieczorek1990 gmail com>]

Hi,
I would like to propose a new 'Save as merge output' feature.
As git mergetool does automatically start meld with LOCAL, BASE and 
REMOTE, it would be nice to have an option to save one of those three as 
merge output, so that the user won't have to use 'Save as' and search 
for file.
Greetings
