Description
Certain uses of grep appear to add extra newlines.
Ex:
Try something like this:
shx ls '~/Music/iTunes' | shx grep 'iTunes'
It acts as expected, producing strings with a single \n for each line.
But
shx ls '~/Music/iTunes' | shx grep '-v' 'iTunes'
appears to add a second newline at the end of the set of strings.
This can be explicitly seen in node:
var sh = require('shelljs')
// terminates with a single newline
sh.ls('~/Music/iTunes').grep('iTunes')
// terminates with two newlines
sh.ls('~/Music/iTunes').grep('-v', 'iTunes')
