# Ignore tidy's exit code because Asciidoc generates section IDs beginning with
# "_", which xmlto converts to "id" attributes of <a> tags. The standard
# insists that "id" attributes begin with a letter, which causes tidy to
# print a warning and return a nonzero code.
# When Asciidoc 8.3.0+ is widespread, I'll use its idprefix attribute instead
# of ignoring return codes.
