Description:
        Draft 6 of POSIX 1003.1-200x says that the shell's "printf" command
        must support the use of apostrophe as a flag character in printf
        specifications.  For example, in a locale that uses "," as a thousands
        separator, bash should behave as follows:

           $ printf "%'d\\n" 1234567
           1,234,567

Repeat-By:
        On a Solaris 7 box, run the following commands.

           export LC_ALL=en_US
           printf "%'d\\n" 1234567

        The output should be "1,234,567", but Bash instead outputs
        "bash: printf: `'': invalid format character".

Fix:

2001-04-26  Paul Eggert  <eggert@twinsun.com>

        * builtins/printf.def (SKIP1): Add "'", as POSIX 1003.1-200x d6
        requires.
