[Docs Update] Documentation about component splitting could use a better example

[LebedevRI]

Description

Let's suppose i have the following, fairly standard, source tree:

• src/dir1/some_name.rs
• src/dir1/tests.rs
• src/dir2/some_name.rs
• src/dir2/tests/something.rs
• src/dir2/tests/other/something.rs

How would one disable default aggregate component, which shows total coverage for everything, and add two non-overlapping components, one for .*/tests.rs$ + .*/tests/.*, and another for everything else, that is not covered by the previous component?

There are mentions of prefixing the pattern with !, but it isn't really obvious how it works.

I would think this is a fairly common situation, so it might be good to explicitly document the solution.
