[RFE] %a support in printf builtin (when available)

[RFE] %a support in printf builtin (when available)

[Vincent Lefevre]

Under Debian/unstable:

dixsept% where printf
printf: shell built-in command
/usr/bin/printf
dixsept% printf "%a\n" 1.1
printf: %a: invalid directive
dixsept% /usr/bin/printf "%a\n" 1.1
0x8.ccccccccccccccdp-3
dixsept%

Note: the %a format appeared in C99.

Also the %a format in now in the POSIX revision draft for the printf
shell utility.

Moreover supporting the ' flag (as defined in the printf function),
like the printf command from the coreutils, would also be useful.
