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.
