Right now, systemlist() doesn't make it possible to tell if the output ended
with a NL or not:
systemlist("cat", "aa\nbb") ==> ['aa', 'bb']
systemlist("cat", "aa\nbb\n") ==> ['aa', 'bb']
This is also inconsistent with it's documentation, which says an empty string
should be added to the output list in the secound case (as with the 'binary'
flag of readfile() ) Possible solution could be to add a flag (similar to
`keepempty` of split() to change this (without breaking code expecting the
present behaviour)
systemlist("cat", "aa\nbb",1) ==> ['aa', 'bb']
systemlist("cat", "aa\nbb\n",1) ==> ['aa', 'bb','']
This would have the nice property that systemlist("cat", somelist) == somelist
systemlist("cat", ['aa','bb'],1) ==> ['aa', 'bb']
systemlist("cat", ['aa','bb',''],1) ==> ['aa', 'bb','']
Best,
Björn
