flow: (v2.x) place with parameter, but without constant prefix, does not match empty path

[x1B]

There is a specific use-case that does not seem to be handled correctly by the flow controller: when a place name consists of just a place parameter (e.g. :some-param) it will match any URL that consists of a single path segment (good), but it will match neither empty URLs nor URLs consisting of just a slash.

This behavior is inconsistent with place definitions that do have a constant prefix. These do match URLs with an empty trailing parameter segment.

Ok, the reason is that some of the regular expressions used in route parameter matching are too specific, demanding a slash before each parameter's colon.

Fixed on master (v2.0.0).
