Tab in Makefile should use tab character, not spaces

Steps to Reproduce:

2. Press "tab", spaces are inserted.

It seems make is the inverse of yaml in the respect http://stackoverflow.com/a/2131227/1156119

To add insult to injury on this one when I set the tab style to tabs it keeps reverting back to spaces every time I switch to another file and then back to the Makefile.

This is still a problem, on Windows too.
Selecting "indent using tabs" or "detect indentation from content"(assuming you have some content in the Makefile already, of course) fixes it, but it's not clear what this is actually doing. After selecting one of those settings, the behavior changes but I do not see any changes to settings files.

This should be fixable by the new language-specific settings possible in VS Code 1.9 (currently in Insiders build, scheduled for release in early February). Details here: https://github.com/Microsoft/vscode-docs/blob/vnext/release-notes/v1_9.md#language-specific-settings

This will allow you to set indentation to tabs for Makefiles, while still keeping it as spaces in other languages if you normally prefer to indent with spaces.
