- Subject: fix printf regression with alt-form octal, zero flag, and field width
- commit b91cdbe2bc8b626aa04dc6e3e84345accf34e4b1, in fixing another
- issue, changed the logic for how alt-form octal adds the leading zero
- to adjust the precision rather than using a prefix character. this
- wrongly suppressed the zero flag by mimicing an explicit precision
- given by the format string. switch back to using a prefix character.
- based on bug report and patch by Dmitry V. Levin, but simplified.
