Hi Nathan, thanks for the report. I'm not sure from reading the
standards whether this behavior really is required. I'm forwarding
upstream.
Hi Herbert, bash, pdks, and posh in unstable do it differently than
dash:
$ bash -c 'K=dvb0.net0 A=${K#dvb} ; echo $A'
0.net0
$ pdksh -c 'K=dvb0.net0 A=${K#dvb} ; echo $A'
0.net0
$ posh -c 'K=dvb0.net0 A=${K#dvb} ; echo $A'
0.net0
$ dash -c 'K=dvb0.net0 A=${K#dvb} ; echo $A'
$
Regards, Gerrit.
