oxfmt's markdown emphasis pass mis-pairs a bare intraword underscore
(N_tree, esp_map.c, auto_sync) with a later _italic_ span in the same
paragraph, corrupting both on the next format run (auto_sync ->
auto*sync). Backticking the identifiers removes the ambiguity and makes
fmt idempotent; fmt:check now passes repo-wide.
