Note that a var(string) of two or more characters means that all of them must match in sequence; this differs from the treatment of two or more characters in the tt(IFS) parameter. See also the tt(=) flag and the tt(SH_WORD_SPLIT) option. + +For historical reasons, the usual behaviour that empty array elements +are retained inside double quotes is disabled for arrays generated +by splitting; hence the following: + +example(line="one::three" +print -l "${(s.:.)line}") + +produces two lines of output for tt(one) and tt(three) and elides the +empty field.
