Add 80 spaces to the end of each line:

Find what: $
Replace with: [80 spaces]

[X] Regular expression

Replace All

To create the 80 spaces:

Create a new document.
Turn on block select mode:
    Configure | Block Select Mode
Go to column 80:
    Search | Go To... | Column 80
Create the spaces:
    <Space>
(If you want to see the spaces: View | Visible Spaces.)
(Turn off block select mode.)
Select the spaces:
    <Shift+Home>
(The satus bar will show: 1 lines, 80 columns selected.)
Copy them:
    <Ctrl+C>
Paste them into the Find what box.

Then chop the lines at column 81:

Turn on block select mode:
    Configure | Block Select Mode.
Go to column 81 in the first line:
    Search | Go To... | Column 81.
Extend the selection a further 80 columns to the right:
    Search | Go To... | Column 161
    [X] Extend selection.
Extend the selection to the last line.
Delete the selection.
(Turn off block select mode.)
