Overview

I noticed the doc comment for actix_router::IntoPattern::is_single was typo'd.

It was probably meant to be "Single pattern", but since the method seems self-documenting enough I just removed it. Please let me know if you'd prefer something else!

The CI job for Windows-mingw failed because of this:

D:\a\actix-net\actix-net>d:\a\_temp\msys\\msys64\usr\bin\bash.exe -ilc "cd $OLDPWD && pacman --noconfirm -S base-devel pkg-config"

Not sure if this is some ephemeral issue or if the CI environment is borked. I force-pushed an amended commit to re-trigger CI; we'll see if it succeeds this time.

I'd just ignore the failures on mingw as it's obviously unrelated and it's enough to test on other platforms in this case.

Thanks!
