Wikidata External ID redirector

This accepts the following '?' parameters and returns a redirect constructed from them:

p - property number (eg. 213 = ISNI)
url_prefix - eg. http://isni.org/
url_suffix - eg. .html
id - the id value of this external id property for an entity of interest

This accepts the alternative '?' parameters:

url - url with parameters %1, %2... eg. http://test.org/?vol=%1&item=%2
exp - regular expression eg. (.*)-(.*)
id - eg. 113-1250
example https://wikidata-externalid-url.toolforge.org/?url=http://test.org/?vol=%1&item=%2&exp=(.*)-(.*)&id=113-1250
result http://test.org/?vol=113?item=1250

Note: all parameters should be url encoded.
Note: this script also URL-decodes the id value so that an id with several embedded parameters can be used as originally intended.

An example: https://wikidata-externalid-url.toolforge.org/?p=213&url_prefix=http://isni.org/&id=0000 0000 8045 6315.
