Subject: mdlinkcheck: only look for markdown links in markdown files
X-Git-Url: https://git.feebdaed.xyz/?a=commitdiff_plain;h=2e3687c60c5c9720992a7cebf9493ec2d28a1cf6;p=0xmirror%2Fcurl.git

mdlinkcheck: only look for markdown links in markdown files

It finds debug outputs in source code otherwise.

Output the whitelist "warnings" to stderr to better allow us to count
URLs with `./mdlinkcheck --dry-run | wc -l`.

Closes #19938
