* compiler: change s.line_nr in just one place, so that s.last_nl_pos will be updated in tandem too.
* v test v: run repl tests again
* Show gcc version in both windows gcc cases in a) github actions, and b) travis .
* adding inline to is_name_char is_nl and contains_capital does not help actually, just increases slightly binary size.
* Cleanup spurious spaces.
