Saving input adds extra new line char

[voberle]

I was doing the 2018 day 5 challenge and my code didn't work. The problem was that the input file downloaded with aoc-cli had a newline at the end. Removing the newline fixed the issue.

Now I don't know if this can be considered a bug, since if I download the input with the browser, there is also a newline at the end. But if I copy-paste it, there isn't one. So I would understand if you reject this bug :-)

Nevertheless IMHO, the client should make it as easy as possible for developers, and so removing this newline would make sense I feel.

FWIW another AoC tool, "cargo-aoc" does such trimming. Here is even the issue where they switched from trim() to trim_end_matches('\n')
