 recheight                                                  *g:aurum_recheight*
     VimL |expression| that evaluates to unsigned integer or unsigned integer. 
     Determines whether |aurum-cs.rev| contains something different from 
     abbreviated hash. If this option is false, then in log produced by 
     |aurum://log| revisions will be ignored.
+    If it is true, then it also assumes that changesets sorted by revision 
+    numbers are sorted in topological order (see |aurum-rf-getchangesets|).
     This key is optional, default value: true.
