If you run an external file with Sonic Pi (such as having some code in the init.rb file) but this external file contains an error, the error is reported, but the location of the error is described confusingly.
For example, in the below screenshot, it exhibits a similar issue to #2334 in that the line number is one off, but in addition, the line number is in relation to the external file. This is not immediately obvious in the current implementation, as errors have only previously been handled from code directly running in the built in buffers. In addition, the location is buffer 'eval', which could use improving.
