In normal variable expansion, setting the option SH_WORD_SPLIT causes
unquoted $var to be equivalent to ${~var} in variable expansion.
Wouldn't it make sense to have SH_WORD_SPLIT activate pattern characters
in unquoted variables in range expressions as well? This would make zsh
under 'emulate sh' exactly compatible with bash, (d)ash, {pd,m}ksh and yash.
