- The <code>-M</code> and <code>-C</code> options require O(n^2) processing time where n
- is the number of potential rename/copy targets. This
- option prevents rename/copy detection from running if
- the number of rename/copy targets exceeds the specified
- number.
+ The <code>-M</code> and <code>-C</code> options involve some preliminary steps that
+ can detect subsets of renames/copies cheaply, followed by an
+ exhaustive fallback portion that compares all remaining
+ unpaired destinations to all relevant sources. (For renames,
+ only remaining unpaired sources are relevant; for copies, all
+ original sources are relevant.) For N sources and
+ destinations, this exhaustive check is O(N^2). This option
+ prevents the exhaustive portion of rename/copy detection from
+ running if the number of source/destination files involved
+ exceeds the specified number. Defaults to diff.renameLimit.
+ Note that a value of 0 is treated as unlimited.
