[ruby-core:114259] [Ruby master Bug#19743] Ruby's parser seems to ignoring DOT at the end of file just after digits

ruby-core #114259
Issue #19743 has been updated by nagachika (Tomoyuki Chikanaga).
Backport changed from 3.0: REQUIRED, 3.1: REQUIRED, 3.2: REQUIRED to 3.0: REQUIRED, 3.1: REQUIRED, 3.2: DONTNEED
Since it's obviously a bug, it had been long-standing and fixing it could break executing existing script.
I don't backport it to ruby_3_2 for now. Any opinion?

* ruby -v: ruby 3.3.0dev (2023-06-19T09:28:10Z master 2a80bac9f0) [x86_64-linux]
* Backport: 3.0: REQUIRED, 3.1: REQUIRED, 3.2: DONTNEED
----------------------------------------
I expect all to be syntax error
~~~ruby
eval "puts 1." #=> 1
eval "puts 1. " #=> syntax error
eval "puts 1.\n" #=> syntax error
~~~
For ripper, period token is missing
~~~ruby
Ripper.tokenize("1.") #=> ["1"]
Ripper.tokenize("1. ") #=> ["1", ".", " "]
~~~
