pub fn preview_list(items: &[String], total: usize) -> StringExpand description
Format a truncated one-line preview of an ordered string list for
inclusion in a status / advice / blocker message. Used by every
verb that would otherwise dump a 50+ item csv onto a single line:
branch lists in status/log/show/doctor, heavy-impact path
lists in status/snapshot/thread/merge, and the
Heavy-impact change: blocker built in repo::thread_advice.
Keeps the first three names and tags the rest as … +N more. The
full list still lives in every JSON form (--output json plus the
verb-specific structured surfaces).
