WAD DO, ECHO, and trailing whitespace

[vefatica]

Can you please change this behavior?

v:\> echos foo^t & echo bar
foo    bar

v:\> (echos foo^t & echo bar)
foo    bar

v:\> do i=1 to 5 (echos foo^t & echo bar)
foobar
foobar
foobar
foobar
foobar

Shouldn't you be doubling the carat in the last example?

Yeah! Thanks! But it doesn't make a heck of a lot of sense (the memorable kind of sense) ... I don't have to double %s but I do have to double ^s.

v:\> do i=1 to 5 (echos %_second^^s & delay 1 )
40 41 42 43 44

WAD - the ( ) in a DO is not a command group, it's a command line to execute. The ^ is parsed and expanded before the DO is executed. This is no different from a FOR argument list.

And no, it can't be changed (but I could remove the DO () syntax if you prefer).
