Download patch does not support binary file change

[hanjun_cho_halla_com]

I work with Bitbucket environment.

As far as I know "Download patch" option in pull request is updated recently. 

I think it needs to update additional option regarding binary files.

If I generate patch file in command line for bianry file patch. I enter those option.

git diff HEAD^ --binary > patch_name.patch 

But in Bitbucket, --binary does not include. 

please add --binary option for binary file change.

it does not affect other source file change.
