Regex fix to avoid matching a trailing slash.

[ericsoco]

The default regex '([^/#?]*)' inserted as a placeholder for matching named patterns matches empty components, such as a trailing slash. This means that a pattern such as /foo/:bar/:baz will match /foo/BAR/, while it should only match foo/BAR/BAZ.

Changing the regex to '([^/#?]+)' to require at least one character in the component keeps trailing slashes from matching the specified path.

Can you add some tests for this? Thanks!

(this is to fix a regression we found after upgrading)
