pub const MAX_VALUE_LEN: usize = 160;Expand description
The longest a single free-text argv value is rendered before it is truncated
with a …(<n> chars) marker. Normal argv (subcommands, flags, refs, paths,
revsets) sits well under this, so it only ever clips genuinely large values —
a PR/issue body, a long commit message — keeping the log both readable and
free of bulk user text. The exact number is not load-bearing.
