syntax_suggest did not work great when there is no new line at the end of the input file. Input: ``` def foo end end # No newline at end of file ``` Previous output: ``` $ ruby test.rb test.rb: --> test.rb Unmatched `end', missing keyword (`do', `def`, `if`, etc.) ? > 1 def foo > 2 end > 3 end # No newline at end of filetest.rb:3: syntax error, unexpected `end' (SyntaxError) end # No newline at end of file ^~~ ``` Note that "test.rb:3: ..." is appended to the last line of the annotation. This change makes sure that the annotation ends with a new line. New output: ``` $ ruby test.rb test.rb: --> test.rb Unmatched `end', missing keyword (`do', `def`, `if`, etc.) ? > 1 def foo > 2 end > 3 end # No newline at end of file test.rb:3: syntax error, unexpected `end' (SyntaxError) end # No newline at end of file ^~~ ``` https://github.com/ruby/syntax_suggest/commit/db4cf9147d
