I didn't know that. This implementation is much more convenient and powerful than TextWrangler's.
Thanks for your prompt support,

Sorry for not stating my idea clearly.
Add and Remove Prefix or Suffix: These actions will prepend or append the supplied string to each line processed (or remove same).
This is how TextWrangler did it:
01. Select multi-line texts you want to add prefix/suffix, choose Prefix/Suffix Lines... from menu

02. Enter prefix and/or suffix values you want in the dialog

03. You have prefix/suffixed added to each lines

04. Now you want to remove suffix. Choose Prefix/Suffix Lines... from menu, then enter suffix value to be removed

05. If lines have same entered suffix, it will be removed as below
