[markdown] Incorrect behavior with certain bracketed text lines
This is similar to issue #107 (closed). In this case, a bracketed string followed by a colon, followed by a single word does not appear. This seems to happen in either code blocks or not. Specifically, I first noticed this in a code block.
[test]: test
[test]: test x
Here is the same text with the colons replaced with underscores.
[test]_ test
[test]_ test x
