Ued has a quirk in the global command which turns out to be of use.

Create a file full of file-names, pip taco=/br  , then remove any headings
so that only the list exists.  Then enter the following commands (s=substitute)

g/./.k..k.		;makes 2 copies, -> every line is now 3
g//+s/.*/"&"/+s/.*/(&)/	;this ends up with:


file1
"file1"
(file1)
file2
"file2"
(file2)
file3
"file3"
(file3)

This example may be reduced to every other line, or increased to more than
3 lines. The bug is that any line globally selected as dot and having a
substitute "up the line" removes the line substituted from the global list.
Thus the next 2 lines get skipped during the execution of the global. If
you experiment with various types you can get pretty wierd but sometimes
interesting results.

see ued2 for additional info.
