* subversion/libsvn_client/mergeinfo.h
  (svn_client__elide_mergeinfo): Tweak the doc string: remove an incorrect
    statement that the abspaths may be relative, following r1415167. Instead,
    like the other private APIs around here, rely on the implicit
    understanding that an argument named 'abspath' is an absolute path.
