[PATCH v2 0/3] sequencer: comment out properly in todo list

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Fix three places where the comment char/string is hardcoded (#) in the todo list.

This series does not depend on any other topics. Topic `jc/strbuf-commented-something` was mentioned on the v1 discussion. But it was kicked out of `seen` last week. Also it doesn’t compile when merged into `v2.47.0` or later:

```
strbuf.c: In function ‘strbuf_add_comment_lines’:
strbuf.c:384:24: error: ‘comment_line_str’ undeclared (first use in this function)
  384 |         add_lines(out, comment_line_str, buf, size, 1);
      |                        ^~~~~~~~~~~~~~~~
strbuf.c:384:24: note: each undeclared identifier is reported only once for each function it appears in
make: *** [Makefile:2795: strbuf.o] Error 1
```

§ Changes in v2

The first version just had patch 1 but this one fixes two other places. The two other places where unearthered during the v1 discussion.

Rebased on `master` (b31fb630c0 (Merge https://github.com/j6t/git-gui, 2024-11-11)).

§ CI

Some failures that didn’t look relevant.

• linux-leaks
  • t0301-credential-cache
  • t9211-scalar-clone
• linux-reftable-leaks
  • ditto above

§ CC

• Stolee for the first patch • Reviewers on the previous round
