See <http://cygwin.com/lists.html#available-lists>. I redirected it to
the right list and set the Reply-To accordingly. I also did so for this
message - please make sure your mailer respects the Reply-To header.

Good. However, "xargs" is the generally used solution for this anyway --
and it's also faster since it doesn't have to build up and then parse the
argument list string.

By "here" do you mean the cygwin-talk list? And where, pray tell, is the
cygwin-talk list mentioned on that page? Or do you mean the "lists.html"
link that mentions cygwin-talk as the list where you could be ridiculed
for asking just about anything? BTW, the "main cygwin list" that it
refers to is <cygwin at cygwin dot com>, which, incidentally, is the list
I redirected your question to.
