// This is necessary because the "source" or "." program in
// bash on OS X closes its file argument before reading
// from it, meaning that you get exactly 1 write, which will
// work most of the time, and will always raise an EPIPE.
//
// Really, one should not be tossing away EPIPE errors, or any
// errors, so casually. But, without this, `. <(npm completion)`
// can never ever work on OS X.
fix: remove trailing spaces Most of the coding style guides ask to remove trailing spaces, also, current .editorconfig has the same config.
