feat(router): remove all trailing slashes for path

[donkeyDau]

Remove trailing slashes but ensure that a single '/' is present.

What's the need for this?

[donkeyDau]

For stripping trailing slashes on the path. I realized that a single trailing slash is stripped but multiple are not.

[donkeyDau]

I was testing around and noticed that stuff breaks if I want to get the last path part on splitting on / and deliberately adding slashes at the end of the path. I've seen that there's a trailing slash handling but not dealing with all the slashes.

Your answer indicates that the trimming of the one trailing slash is a need of the library. If that's the case then imho it should not be exposed as the user (or at least I'm) either expects getting the unchanged path or fully trimmed by trailing slashes.

[donkeyDau]

I can agree with that. To me this looks flawed that's why I wanted to make it "right". I'm also fine removing the whole line. Anyhow this would be a breaking change. Maybe it'll be integrated in a v3 ...

Upon more thought, you sold me.

If you want to add a test (I can do so a bit later, alternatively), let's just get this in.

[rschristian]

I appreciate you bearing with me.

I'm still back and forth on trailing slashes re:URLPattern, but this I'm fine with this for now. Bare is a bit nicer to look at anyhow, so I'm thinking bare will be the preference and we'll internally always coerce to it.
