[Bug] Import markdown, the URL with username and password in the code block is abnormally converted

[apomalyn]

Was able to reproduce it on v0.5.3. You don't need to import the file.

Step to reproduce:

1. Add a code block of Auto or Bash (maybe other works but I only tested those two)
2. In the code block, add any text that ressemble a email address. E.g.: [email protected]
3. Export as markdown (Share > Markdown)

I think the editor is also concerned because, with Auto, email-like string are coloured even when part of an URL.
