I'm currently working on a patch to split isFromMainFile into two versions; one which respects line markers (after '# 1 "XXX.h" 1', we treat the following lines as not part of the main file), and one which has the current behavior.  I think you want the behavior which respects line markers, but I'm not completely sure how you expect this to be used.

For the use case that led me to add this, I want to know if it's physically in the main source file. I can see how the line marker behaviour would be helpful too (actually I may want that behaviour in addition myself).

I think this should probably be exposed through a parameter in the libclang function (PhysicalOnly or RespectLineMarkers or something along those lines) and expect it should still be fine to change the API since it was added so recently (but I don't know if there's a specific rule about that).
