From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linus Torvalds Injects Tabs To Thwart Kconfig Parsers Not Correctly Handling Them (www.phoronix.com)

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.

I am no kernel or parsing expert here but how hard would it be to convert tabs to spaces? Is it like very finicky and is weirdly platform dependent that it wouldn't just be one of the first things that you do if you are writing a parser for anything?

grep -oP ' *' oops no tabs

cut -d ' ' -f 3 oops no tabs
