    there is at least one (#i)Temp dir
    
    ... Very slick.  I can have a matching *file* but it ignores that
    and captures the directory.  
    
    ... But,  I want it to fail if there's more than one directory
    match:
    
    2 /aWorking/Zsh/Source/Wk 3 % md tEMP # Torture testing.
    
    2 /aWorking/Zsh/Source/Wk 3 % [[ -n ''(#i)Temp(#qN/) ]] &&
    echo "there is at least one (#i)Temp dir"
    there is at least one (#i)Temp dir  # I'd want it to fail here.
    
    2 /aWorking/Zsh/Source/Wk 3 % [[ -d ''(#i)temp(#qN) ]] &&
    echo "it's a directory"
    
    ... so your original is safer.  It would be tempting the Gods to to
    want it to only accept one possible directory but ignore matching
    files.
    
    The basic idea is that my wrapper will show the contents of a
    directory if there is a single match:
    
    2 /aWorking/Zsh/Source/Wk 3 % l Temp  # There's only one match so
    directory contents:
    
    CONTENTS of "Temp": All file types, Implied Sensitive. Sorting
    oldest on top by modification time:
    
     0 [26-04-10--10:17] garbage
    
    Items found: 1
    Total bytes in directory "/aWorking/Zsh/Source/Wk/Temp": 4.0K
    Total including subdirs: 4.0K
    
    ... but when there's more than one match, show a normal 'local'
    listing:
    
    2 /aWorking/Zsh/Source/Wk 3 % try l && l ,v temp
    Sourcing l
    
     4096 [26-04-10--10:17] Temp/
     4096 [26-04-10--11:39] tEMP/
        0 [26-04-10--11:35] temp
    
    ... two directories and one file.
    
    But, it occurred to me that the directory search could be case
    insensitive as desired.  But there must only be only one unambiguous
    match, as before.  And the thing should abort if there's any
    matching files cuz then you'd not have the 'local' listing which is
    what would normally be wanted.  Come to think of it, this might be a
    bad idea.  Yup, I'll leave it as it is -- one exact match or bust.  
    
    But I'll save your code, that's to be stored for a future day.
