docs/coding_conventions_c.md VS clang-format

[mtei]

In docs/coding_conventions_c.md it says the following:

qmk_firmware/docs/coding_conventions_c.md

Line 23 in 59188bf

* Do not put whitespace between `#` and `if`.

However, the .clang-format is set up as follows:

qmk_firmware/.clang-format

Line 15 in 59188bf

IndentPPDirectives: AfterHash

If you follow docs/coding_conventions_c.md, the .clang-format setting should look like this:

IndentPPDirectives: BeforeHash 

And I prefer the provision in docs/coding_conventions_c.md.

The issue with BeforeHash is that since it's a relatively recent addition to clang-format, it may not be recognised for some users as most platforms don't provide the latest versions. We've gone with AfterHash for the time being so that there is at least some structure to them.

See #6316.

I understand. Thank you.

[vomindoraan]

Would it make sense to update the coding conventions to match .clang-format, for the time being? This may help prevent further confusion until we are ready to fully transition to BeforeHash.

[fauxpark]

Yeah, a bit of explanation on the current situation is probably called for.
