Upstream changes:
1.70 2016-12-10
- Altered the conversion specifier %z to accept 簣HH, 簣HHMM, 簣HH:MM and Z.
Previously only 簣HHMM where accepted. PR from Christian Hansen, GitHub #13.
1.69 2016-12-04 (TRIAL RELEASE)
- The word boundary check supposedly added in 1.67 didn't really work
properly, and still matched too much. For example, the pattern "%d-%m-%y"
would match "2016-11-30" and turn it into November 16, 2030. This also had
problems at the end of strings, so that the same pattern would improperly
match "30-11-2016" as November 30, 2020. Reported by Erik Huelsmann. GitHub
#11.
- Added docs for several formats which had long been supported but not
documented. These are %P, %c, %x, and %X. Reported by Alexander
Hartmaier. GH #10.
