Emacs: Quote Lines 🚀

Here's a command to convert lines to quoted lines.

For example,

cat
dog
cow

becomes

"cat",
"dog",
"cow",

or with any other quote character:

'cat',
'dog',
'cow',

or without comma:

"cat"
"dog"
"cow"

or with any type of brackets:

(cat)
(dog)
(cow)

Here it is.

(defun xah-quote-lines (QuoteL QuoteR Sep)
  "Add quotes/brackets and separator (comma) to lines.
Act on current block or selection.

For example,

 cat
 dog
 cow

becomes

 \"cat\",
 \"dog\",
 \"cow\",

or

 (cat)
 (dog)
 (cow)

In lisp code, QuoteL QuoteR Sep are strings.
