ValueError: invalid literal for int() with base 10: '?25'

An unexpected error occurred while reading:
/home/gaz/src/bitplane.net/~/doc/thoughts/lens/words/src/1.1.library.ans

Why?

chafa turns the cursor off when it draws and on again afterwards:

• ^[[?25l (hide)
• ^[[?25h (show)

stransi tries to int('?25') and fails. This bug and fix have been open for a while, so it might be better to filter here or patch it or something.

Use chafa --polite on.
