processed John Dalbec's fix of 2000/dlowe

Updated `bugs.html` to reflect the fix of all known bugs in `2000/dlowe`.

Added thank you to John Dalbec in `thanks-for-help.md`.

Added processing of "%%REPO_TOP_URL%%" tokens to `bin/subst.default.sh`.

Updated `find-missing-links.sh` to not falsely report missing links
when a "%%REPO_TOP_URL%%" token is used.

Changed `bin/subst.default.sh` VERSION from "1.3.2 2024-08-05"
to "1.4.0 2025-04-16".

Changed `bin/find-missing-links.sh` VERSION from "1.1.1 2024-04-28"
to "1.2.0 2025-04-16".

Due to a `pandoc(1)` bug fix, `2011/fredriksson/index.html` and
`2012/kang/index.html` were modified.  The bug fix removed extraneous
whitespace that was previously introduced into HTML under certain
situations.  These 2 changes do **NOT** impact the way web browsers
render these pages, however.

Updated sitemap.

Tested the above via `make www gen_status gen_sitemap timestamp` on macOS.
