printf: allow 0 as a flag and allow multiple flags

2021-12-17T20:13:26+00:00

The '%' character in a format specification may be followed by
one or more flags from the list "+- #0".  BusyBox printf didn't
support the '0' flag or allow multiple flags to be provided.
As a result the formats '%0*d' and '%0 d' were considered to be
invalid.

The lack of support for '0' was pointed out by Andrew Snyder on the
musl mailing list:

awk: fix printf %%

2021-09-05T01:42:51+00:00

A refactor of the awk printf code in
e2e3802987266c98df0efdf40ad5da4b07df0113
appears to have broken the printf interpretation of two percent signs,
which normally outputs only one percent sign.

The patch below brings busybox awk printf behavior back into alignment
with the pre-e2e380 behavior, the busybox printf util, and other common
(awk and non-awk) printf implementations.

Thanks to Cristian Ionescu-Idbohrn for noticing.

Also fix "%d" '  42' to skip leading whitespace.

Tweak some tests so they work when the path to the test directory or
$HOME contains spaces.

Fix some test cases

2010-09-03T15:09:51+00:00

The tar tests still don't pass, but at least now it's because of
a problem with Busybox and not the tests themselves.

*: make GNU licensing statement forms more regular

2010-08-16T18:14:46+00:00

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

tests: fix POSIX shell source style

2009-11-04T23:41:22+00:00

The source command does not search $PWD, and bash recently fixed itself to
follow this behavior for /bin/sh.
