date: too much whitespace for %e format (#987)

* I was tracking why the Perl date command separated Mar and 14 with 2 spaces instead of one
* The default strftime() format string is "%a %b %e %T %Z %Y"
* The Linux manual for strftime() says %e is the same as %d, except that a leading zero is replaced with a leading space
* So day 1 would be "01" and " 1", but day 10 would have no leading space/zero
* Formatting the day number with "%2d" is good enough for %e specifier; previously day 14 was formatted as " 14" in setup_specifiers()
