2.8 for loop

Because Eshell commands can not (easily) be combined with lisp forms, Eshell provides a command-oriented for-loop for convenience. The syntax is as follows:

     for VAR in TOKENS { command invocation(s) }

where ‘TOKENS’ is a space-separated sequence of values of VAR for each iteration. This can even be the output of a command if ‘TOKENS’ is replaced with ‘{ command invocation }’.
