Specify which documentation you found a problem with

The problem is in the curl manual page up to 8.11.1 assuming https://curl.se/docs/manpage.html is up to date.
This is more a quality-of-life issue than an error.

The problem

It's not entirely obvious on initial inspection why curl isn't forwarding -H "Authorization: ..." (which where manual implies -H is permanent, though presumably curl specifically strips the Authorization header subsequently..) or -u use:pass when following redirects according to -L . The -L documentation does describe the problem and cross references to --location-trusted, but for me it was more intuitive to look under -H and -u when I initially discovered the "missing" authorization headers in -v output.

-H (which is more generic) and -u give no mention of stripping (under redirects).
