Disable reference generation in preformatted/code blocks ### Summary If a user adds text in code or preformatted text via Markdown or HTML that contains `#XXX`, the system adds a note that issue `XXX` was mentioned. This is particularly annoying because we often list gdb backtrace dumps into our issues, and many issues get mentioned as a result. For example: ``` (gdb) bt #0 0x00000000004004c4 in second () at main.cc:6 #1 0x00000000004004d2 in first () at main.cc:11 #2 0x00000000004004dd in main () at main.cc:17 (gdb) ``` ### Steps to reproduce 1. In an issue, write the above text using Markdown or HTML tags (e.g. `<code>`, `<pre>`). 2. Observe that [issue 1](https://gitlab.com/gitlab-org/gitlab-ce/issues/1) and [issue 2](https://gitlab.com/gitlab-org/gitlab-ce/issues/2) have a note that says they were mentioned. ### Expected behavior Everything enclosed in the code blocks should be ignored as references. ### Observed behavior Issues get referenced unnecessarily. ### Fix I've made `reference_extractor.rb` strip out HTML and Markdown blocks before processing. I considered running the raw text through the entire Markdown processor, but this seems overkill and perhaps could lead to some unintended side effects. See merge request !365
