Use of the showPlus format flag

Pantheios 1.0.1 beta 215 introduces the showPlus format flag, which causes leading pluses to be applied to integers (just as leading minuses will appear for negative numbers).

It is used as follows:

#include <pantheios/pan.hpp>
#include <pantheios/inserters/i.hpp>

int main()
{
  pan::log_INFORMATIONAL("log -10:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(-10, 0, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");

  pan::log_INFORMATIONAL("log +10:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(+10, 0, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");


  pan::log_INFORMATIONAL("log -10 into 10-width:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10, 10, 0), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(-10, 10, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");

  pan::log_INFORMATIONAL("log +10 into 10-width:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10, 10, 0), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(+10, 10, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");


  pan::log_INFORMATIONAL("log -10 into 10-width left-justified:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10, -10, 0), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(-10, -10, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");

  pan::log_INFORMATIONAL("log +10 into 10-width left-justified:");
  pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10, -10, 0), "'");
  pan::log_INFORMATIONAL("with    showPlus: '", pan::i(+10, -10, pan::fmt::showPlus), "'");
  pan::log_INFORMATIONAL("----------\n");


  return 0;
}

PANTHEIOS_EXTERN_C PAN_CHAR_T const PANTHEIOS_FE_PROCESS_IDENTITY[] = PANTHEIOS_LITERAL_STRING("test.scratch.showPlus.integer");

which gives the output:
