Wikicreole line breaks not working in cases with colons?

[benjamin.a.lau@…]

Having a weird issue with the wikicreole line break syntax.

Issue wiki markup

Issue rendering

These don't all render correctly. The first just the first line break renders.

In the second none of the line breaks render.

In the last one I removed the : in 8:30pm and then it renders correctly. On the trac instance where I encountered this I also noticed that if I put spaces around the \\ it'll render correct. And I can replace the : with : and make it work (which is a feature of the ​WikiExtras plug-in).

I'm guessing I'm looking for some edge case in the wiki parser.

This is not a defect. I suggest closing as wontfix.

                          ^^^^^^^^^^^^^^ Trac is parsing as a URI

Examples:

12345:x\\y	12345:x y	not URI
a:x\\y	a:x\\y	a:x\\y is a URI
1a:x\\y	1a:x\\y	a:x\\y is a URI
1http://x\\y	1​http://x\\y	http://x\\y is a URI

But that string starts with a number (even if a sub-portion of it is a uri) which isn't valid for the scheme portion of a uri. From wikipedia ​URL:

A non-empty scheme component followed by a colon (:), consisting of a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus (+), period (.), or hyphen (-).

By that definition 12345:x\\y, 1a:x\\y, and 1http://x\\y are not valid URIs
