Fixing goes fast if people are out there testing things.  Thanks for 
your report.

This is because SPACE does completion in the minibuffer.  Hmm.  Ok, I 
can turn this default off  and make SPACE insert itself.  This means 
that only TAB will do completion in the minibuffer at the C-c C-l 
prompt. Not a problem, I guess.

The command is there, it is only invisible because it is a copy of the 
invisible command in the [[ ]] link :-).  I am removing this 
invisibility property now.

In the hidden part of a link, space and brackets are escaped.  I forgot 
to unescape for the editing prompt.

While I was at it, I have also removed the restrictions on shell 
commands.  Shell: links in [[ ]] brackets can now contain "<", ">", and 
"|".  These restrictions were only needed in <> links, but now no 
longer.  This is nice.

Also, maybe you'd like to know that there is a variable to turn off the 
safety query in shell links: org-confirm-shell-links.  I could also 
change the yes-or-no query to a y-or-n query to make it easier to 
answer....  We'll see, not now.
