Compiler errors don't highlight corresponding line of code. #2737
Description
In past Arduino versions, when compiling a sketch the line of code corresponding to the first error would be highlighted. This was a big help in assisting users in locating (and fixing) the error, without necessarily needing to read through the (often-confusing) error message in detail. At some point, this behavior seems to have stopped. For example, I don't see it in the latest master branch (1.6.1) on Mac OS X (10.10.2). It would be great to bring back this functionality.
