* pan/unicode_printable_ranges:
  Adapt stdlib tests to ~tp detecting latin1 binaries
  Update primary bootstrap
  Make wx debugger use +pc flag when applicable
  Correct misspelled comments and space at lin ends
  Make ~tp output latin1 binaries as strings if possible
  Leave the +pc handling to io and io_lib_pretty
  Remove newly introduced warning in erlexec.c
  Make shell_SUITE:otp_10302 use +pc unicode when needed
  Fix io_proto_SUITE to handle the new io_lib_pretty:print
  Add testcase for +pc and io:printable_range/0
  Make printing of UTF-8 in binaries behave like lists.
  Document +pc flag and io:printable_range/0
  Add usage of and spec for io:printable_range/0
