touch "o rly?"
While many of these are false alarms (numbers, fixed names, ...), the
problem is real. Sometimes you even have a proper and improper usage on the
same or on subsequent lines:
(/etc/mc/mc.menu)
case "$i" in
*.tar.gz) D="`basename $i .tar.gz`";;
Especially files that came from Windows are likely to have spaces in their
names.
I just don't get why posion singles out $i among all other possible variable
names. Or /etc/ when that's not the main place where you find scripts in.
