ISO C23 redefines strchr and friends that tradiotionally took
a const pointer and returned a non-const pointer derived from it to

If the body of a commit message contains a diff that is not indented
then "git am" will treat that diff as part of the patch rather than
as part of the commit message. This allows it to apply email messages
that were created by adding a commit message in front of a regular diff
without adding the "---" separator used by "git format-patch". This
often surprises users [1-4] so add a check to the sample "commit-msg"
hook to reject messages that would confuse "git am". Even if a project
does not use an email based workflow it is not uncommon for people
to generate patches from it and apply them with "git am". Therefore
it is still worth discouraging the creation of commit messages that
would not be applied correctly.
A further source of confusion when applying patches with "git am" is
the "---" separator that is added by "git format patch". If a commit
message body contains that line then it will be truncated by "git am".
As this is often used by patch authors to add some commentary that
they do not want to end up in the commit message when the patch is
applied, the hook does not complain about the presence of "---" lines
in the message.
Detecting if the message contains a diff is complicated by the
hook being passed the message before it is cleaned up so we need to
ignore any diffs below the scissors line. There are also two possible
config keys to check to find the comment character at the start of
the scissors line. The first paragraph of the commit message becomes
the email subject header which beings "Subject: " and so does not
need to be checked. The trailing ".*" when matching commented lines
ensures that if the comment string ends with a "$" it is not treated
as an anchor.

git-format-patch(1) and git-am(1) deal with formatting commits as
patches and applying them, respectively. Naturally they use a few
delimiters to mark where the commit message ends. This can lead to
surprising behavior when these delimiters are used in the commit
message itself.
git-format-patch(1) will accept any commit message and not warn or error
about these delimiters being used.[1]
Especially problematic is the presence of unindented diffs in the commit
message; the patch machinery will naturally (since the commit message
has ended) try to apply that diff and everything after it.[2]
It is unclear whether any commands in this chain will learn to warn
about this. One concern could be that users have learned to rely on
the three-dash line rule to conveniently add extra-commit message
information in the commit message, knowing that git-am(1) will
ignore it.[4]
All of this is covered already, technically. However, we should spell
out the implications.
† 1: There is also git-commit(1) to consider. However, making that
command warn or error out over such delimiters would be disruptive
to all Git users who never use email in their workflow.
† 2: Recently patch(1) caused this issue for a project, but it was noted
that git-am(1) has the same behavior[3]

For a line to be an anchor it has to appear in each of the files being
diffed exactly once. With that in mind lets delay checking whether
a line is an anchor until we know there is exactly one instance of
the line in each file. As each line is checked at most once, there
is no need to cache the result of is_anchor() and we can drop that
field from the hashmap entries. When diffing 5000 recent commits in
git.git this gives a modest speedup of ~2%. In the (rather extreme)
example below that consists largely of deletions the speedup is ~16%.
seq 0 10000000 >old
printf '%s\n' 300000 100000 200000 >new
git diff --no-index --anchored=300000 old new
