If this is related to Outreachy, it would be better to put "[Outreachy]" at the start of the subject.
Replace manual buffer checks with starts_with() for safety and clarity. This avoids buffer overreads and follows Git's idiomatic style used
It looks like the above sentence is not finished. Maybe s/ used/./ ?

A lot of lines seem to be changed for a patch that wants to use starts_with() in fsck_commit(). Let's see below.

If a patch does other things than it's main goal, it should be mentioned in the commit message that it's doing those other things "while at it". Anyway when I look at fsck_commit() in "fsck.c" on 'master', it seems to me that the function is properly indented. So I suspect that your patch changes its indentation for no good reason.
{
- struct object_id tree_oid, parent_oid;
- unsigned author_count;
- int err;
- const char *buffer_begin = buffer;
- const char *buffer_end = buffer + size;
- const char *p;
+ struct object_id tree_oid, parent_oid;
+ unsigned author_count = 0;
+ int err = 0;
+ const char *buffer_end = buffer + size;
+ const char *p;Here also I suspect that the indentation changes are not necessary. They are also making it more difficult to spot actual changes like 'buffer_begin' being removed and 'author_count' and 'err' being initialized to 0. Sorry I am stopping my review here as there seems to be too many indentation changes that are masking the actual changes. Please make sure you send patches that don't change the indentation for no good reason. Thanks.
