0066-ps/sortformat.c: Handle large width in aix_format_parse().

Browse Source 
Unlikely to ever happen, since it would imply a very large string, but
better safe than sorry.

---------------------------- adapted for newlib branch
. now uses 'xmalloc' vs. unchecked stdlib 'malloc'
. the member 'need' was removed from 'format_node'
