Comment:
In case it isn't clear from the previous comment:
* GHC uses `#line` pragmas to determine what source files were visited by
the C preprocessor, and tracks dependencies on these for recompilation
* The lexer currently ignores `#line` pragmas inside `{- .. -}` comments,
and hence it misses any preprocessor dependencies inside `{- .. -}`
I'm raising the priority of this bug.
