Use digits in suffixes rather than lower-case letters. The numerical
suffix counts from @var{from} if specified, 0 otherwise.

+@var{from} is used to either set the initial suffix for a single run,
+or to set the suffix offset for independently split inputs, and consequently
+the auto suffix length expansion described above is disabled. Therefore
+you may also want to use option @option{-a} to allow suffixes beyond @samp{99}.
+Note if option @option{--number} is specified and the number of files is less
+than @var{from}, a single run is assumed and the minimum suffix length
+required is automatically determined.
