Subject: [ruby-core:78099] [Ruby trunk Feature#12926] -l flag for line end processing should use chomp! instead of chop!

Issue #12926 has been reported by Josh Cheek.

Feature #12926: -l flag for line end processing should use chomp! instead of chop!

----------------------------------------
Using `chop!` can mess up the final line of input because it may not end in a line-end character.

```
printf a\\nb\\nc | ruby -lne 'p $_'
"a"
"b"
""


$ printf a\\nb\\nc\\n | ruby -lne 'p $_'
"a"
"b"
"c"
```


Using `chomp!` works correctly in both cases.

```
$ printf a\\nb\\nc | ruby -ne '$_.chomp!; p $_'
"a"
"b"
"c"

$ printf a\\nb\\nc\\n | ruby -ne '$_.chomp!; p $_'
"a"
"b"
"c"
```
