Currently checkpatch.pl prints an error if I use 8 or more spaces in the
indentation string and Documentation/CodingStyle says:

"Outside of comments, documentation and except in Kconfig, spaces are never
used for indentation"

Although CodingStyle and checkpatch just provide guidance and the final
word is the maintainer's I consider these recommendations as "disallowing",
or at least "discouraging". So did others that commented on patches I sent
in the past.  If that wasn't the case I wouldn't have come up with this
silly initiative in the first place.

I'm certainly not advocating to prohibit the current indentation style,
just to relax the rules to allow a superset of it.

Basically, I'd like checkpatch to allow /^\+\t* *\S/
and, since Andy says that checkpatch knows "the indent to some degree",
it can warn if the number of leading tabs is smaller than that.

No, I don't mind.

[Though it is a bit of a pain to keep that when automatic wrapping of long
lines is turned off in my mail program so I can easily quote patches or
code snippets.]
