- Linus Torvalds added hidden tabs to Kconfig to challenge parsers that can’t handle them.
- Tabs were intentionally added to the common Kconfig file for page sizes to expose faulty parsers.
- Torvalds believes parsers unable to handle tabs shouldn’t be parsing kernel Kconfig files, aiming to force fixes.
Why would anyone NOT parse a tab as whitespace? Like, python really wants you to use spaces but will still let you use tabs if you are consistent.
