Bug #10582: String#chomp strips off more newlines than its documentation states

• Status: Closed

[javawizard (Alex Boyd)]

Given an empty string as its parameter, String#chomp strips off as many trailing newlines as are present, plus a preceding carriage return if one exists:

irb(main):001:0> "foo\n\n\n".chomp
=> "foo\n\n"
irb(main):002:0> "foo\n\n\n".chomp ''
=> "foo"
irb(main):003:0> "foo\r\n\n\n".chomp ''
=> "foo"

This should either be mentioned as part of String#chomp's documentation, or removed.
