shell links [was: Version 4.19c]

[Scott Otterson <scotto@u.washington.edu>]

Lot's of nice changes in 4.19.  I'm really impressed at how fast Carsten 
& Co. are cranking out new code and new fixes.

Looks like there are a few problems with shell links in 4.19c, though.

1.) If I type C-c C-l, and then at the link: prompt, type

     shell:SPACE

    where SPACE means I hit the spacebar, then I get a [No Match] error
    message.  If I instead type:

     shell:lsSPACE

    then I get the [No Match] error after the 'ls'

2.) If I manually make a shell link like this

      [[shell:ls *.org][shellcmd]]

     and then type C-c C-o.  The minibuffer asks m:


       Execute " " in the shel? (yes or no)

     Even though there's a blank, the ls command works if I say yes

3.) If I put the cursor in the link and type C-c C-l, then
      the minibuffer says:

      Link: shell:ls%20*.org

     If I cancel (C-g), C-c C-o still works.
