Come on, this was in the Single UNIX Specification Version 2 from 1997,
and Solaris 10's /usr/xpg4/bin/sh groks it:
$ uname -a
SunOS somehost 5.10 Generic_142900-03 sun4u sparc SUNW,Ultra-5_10
$ /usr/xpg4/bin/sh -c 'a=foo ; echo ${a%oo}'
f
You may need to force the xpg4 shell to be used (bogofilter does that,
read its *.a[cm] files if you need to know how, it's on
sourceforge.net), but other than that, we should not waste any efforts
on systems that violate 15-year-old standards.
