If incremental recursion is active (see bf(--recursive)), rsync may transfer
a missing hard-linked file before it finds that another link for that contents
exists elsewhere in the hierarchy. This does not affect the accuracy of
-the transfer, just its efficiency. One way to avoid this is to disable
+the transfer (i.e. which files are hard-linked together), just its efficiency
+(i.e. copying the data for a new, early copy of a hard-linked file that could
+have been found later in the transfer in another member of the hard-linked
+set of files). One way to avoid this inefficiency is to disable
incremental recursion using the bf(--no-inc-recursive) option.
dit(bf(-p, --perms)) This option causes the receiving rsync to set the
filenames will be translated from the sending host's charset to the
receiving host's charset.
+NOTE: sorting the list of files in the --files-from input helps rsync to be
+more efficient, as it will avoid re-visiting the path elements that are shared
+between adjacent entries. If the input is not sorted, some path elements
+(implied directories) may end up being scanned multiple times, and rsync will
+eventually unduplicate them after they get turned into file-list elements.

dit(bf(-0, --from0)) This tells rsync that the rules/filenames it reads from a
file are terminated by a null ('\0') character, not a NL, CR, or CR+LF.
This affects bf(--exclude-from), bf(--include-from), bf(--files-from), and any
