Minify error lacks file context

[gzip]

I'm running a file through shifter which contains many yui modules. It gets split into separate files and one of them throws an error during uglify. The error message contains a line and col but lacks a filename. I discussed the issue with @caridy.

I will take this one.

Note that I was able to narrow down the file by installing yuglify globally and running: yuglify yui-build/*/*.js
