Hi all,

with the following simple snippet of Ruby code:

``` ruby
def x.y.z
end

```

the interpreter raises a `SyntaxError`, whose message is made up of two sentences with no spaces or punctuation in between (see line no. 2 of the output):

``` shell
scratch2.rb: --> scratch2.rb
expected a delimiter to close the parametersunexpected '.', ignoring it
...
1  def x.y.z
2  end
scratch2.rb:1: syntax errors found (SyntaxError)
...
1 | def x.y.z
    |        ^ unexpected '.', ignoring it
    |        ^ expected a delimiter to close the parameters
  2 | end
  3 |

This happens on master with the sentences reported above, but also on 3.3.5 with the sentences:
`expected a delimiter to close the parameterscannot parse the expression`.

Unfortunately I can't tell if the same glitch occurs with other error messages.

Thanks!
