Details:

Note that this is likely a bug in Savanae software itself.

While I was writing GNU Screen bug #57219 submission, I attempted to add an
inline link to a page on Internet Archive with following markup:

Title Prompt
<http://web.archive.org/web/20121226203910/http://www.gnu.org/software/screen/manual/html_node/Title-Prompts.html#Title-Prompts>

* Note that the URL has `http://` in the middle, but is nevertheless intended
and valid.

I expected the code above to produce a link text "Title Prompt", with URL
pointing to the Internet Archive entry of GNU Screen's HTML manual page.

But once I wrote this in some random bug's comment, and clicked "Preview", it
ended up producing following text instead:

http://web.archive.org/web/20121226203910/Title Prompt
<http://www.gnu.org/software/screen/manual/html_node/Title-Prompts.html#Title-Prompts>

*which is nonsensical, and also linked to an incorrect place* as `[` got
sandwiched inside the URL.

Current workaround is to avoid the inline link markup entirely, and write the
URL literally, like:

http://web.archive.org/web/20121226203910/http://www.gnu.org/software/screen/manual/html_node/Title-Prompts.html#Title-Prompts

which still produce a correct link.

Please investigate and fix.

P.S. Apart from `http://`, `https://` in the link is also trigger this; no
matter it was the one in the front, the middle, or both.
