Sort should silently add a newline to the last line of input if it is missing

[charles-randall]

@mayank-02 Are you getting notified of these?

See the INPUT FILES section of this document,

https://www.unix.com/man-page/posix/1p/sort/

INPUT FILES

The input files shall be text files, except that the sort utility shall add a newline to the end of a file ending with an incomplete last line.

GNU sort,
$ echo -ne "a\nb\nc" | sort
a
b
c
$

msort,
$ echo -ne "a\nb\nc" | msort
a
b
c$

Thanks for pointing it out. I was notified, but didn't get the time to check right away. I'll need some time to incorporate the couple of issues you brought forward. Meanwhile feel free to go ahead and create pull requests for the same.
