Exit code 1, but does not report any issues with -v passed when []() syntax is used instead of []() for links

[suricactus]

Pretty much the title.

Create a markdown file that defines a "link" like this: (link)[https://github.com] . Instead of showing "invalid link syntax" for a given file, or anything, I get a silent exit code 1.

Note that if a file has no links to be checked and I pass the verbose mode, I get:

FILE: markdown.md
  No hyperlinks found!

  0 links checked.

But when in this case I just got:

FILE: markdown.md

Without any further explanations if any links were checked.

Took me a while to discover what went wrong.

Not related to #369 , but haven't checked against #398 .

Are you using a config file ? Which version are you using ?

[suricactus]

I tried with and without config file, tried all the version above v3.11.2 till latest.

I was able to reproduce the issue and have a little bit more datas

An error is raised here https://github.com/tcort/link-check/blob/3263c3b65917375c209928ca2b1ad4102824da36/index.js#L21 when trying to convert what's supposed to be an URL to en URL object

If you have a look to the logs here above, it has discovered your "wrong" url but as it's not in the right format it kept the ] at the end (%5D). I don't know how it works in details and why it's not displayed to the console
