----------------------------------------
Bug #18909: ARGF.readlines reads more than current file
https://bugs.ruby-lang.org/issues/18909#change-99809

* Author: JohanJosefsson (Johan Josefsson)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
* Backport: 2.7: REQUIRED, 3.0: REQUIRED, 3.1: DONE
----------------------------------------
The docuentation says that ARGF.readlines: *Reads ARGF's current file in its entirety* , but this is what happens:

`$ cat fileA
A
$ cat fileB
B
$ ruby -e 'puts ARGF.readlines' fileA fileB
A
B`
i.e. it reads both the current file and the next one (all files?).
