That says _what_ the patch does. We care more deeply about _why_ it is a good idea for a patch to do so. And ...

Something like this, perhaps?
    Subject: [PATCH] bundle-uri: send debug output to given FILE * stream
    d796cedb (bundle-uri: unit test "key=value" parsing, 2022-10-12)
    introduced the print_bundle_list() function, which takes a "FILE
    *fp" to write the output to.  Later with c93c3d2f (bundle-uri:
    parse bundle.heuristic=creationToken, 2023-01-31) the function
    started showing additional information, which is always written
    to the standard output stream.
    It does not look like a deliberate decision to do so, and it
    does not hurt, as all callers of the function passes stdout to
    it.
    
    We could change the function not to take fp and always write to
    the standard output to simplify, but let's use the FILE *fp
    provided by the caller consistently to write out output.
The change the patch makes looks obviously correct.
Thanks.

[PATCH v2] bundle-uri: send debug output to given FILE * stream

From: Jan Mazur <mzr@fb.com>

d796cedb (bundle-uri: unit test "key=value" parsing, 2022-10-12) introduced the print_bundle_list() function, which takes a "FILE *fp" to write the output to. Later with c93c3d2f (bundle-uri: parse bundle.heuristic=creationToken, 2023-01-31) the function started showing additional information, which is always written to the standard output stream.

It does not look like a deliberate decision to do so, and it does not hurt, as all callers of the function passes stdout to it.

We could change the function not to take fp and always write to the standard output to simplify, but let's use the FILE *fp provided by the caller consistently to write out output.
