Provide a way to pass arbitrary strings to executed commands (likely with TIP 424)

[xoich]

With the exec command it's not possible to pass arbitrary strings to commands, because of the special arguments like | and >filename. TIP #424 extends the exec syntax so that a list of raw arguments can be passed to it.

Actually I have had an implementation of TIP 424 for a while, that I think is may just be missing some documentation.
I just pushed it to branch exec-tip424

You are welcome to try it and report back. Updated documentation is also welcome.

Fantastic, thank you @msteveb! I tried and it seems to work right. I noticed that In the manual you added the change in the section "Changes between 0.81 and 0.82", shouldn't it be in "Changes since 0.82"?

Thanks. Blame the quick automated merge. I'll fix that when I tidy up the branch before merging. Will likely be a while since I'm too busy right now to write documentation
