In zsh:

$ echo whatever:/**
whatever:/**

Quick check with:
ksh-20100621-12.el6.x86_64,
dash-0.5.5.1-3.1.el6.x86_64
busybox-1.15.1-20.el6.x86_64 (busybox sh & busybox ash)
and
http://sourceforge.net/projects/heirloom/files/heirloom-sh/050706/heirloom-sh-050706.tar.bz2/download

all do the same (non-)expansion.


I vaguely remember some shells did puke some error when expansion yielded
no results... maybe some shell option does it. Definitely not mainstream
feature.
