/**
 * Returns mergeinfo as a <code>Map</code> with merge source URLs (as
 * {@link SVNURL}) mapped to range lists ({@link SVNMergeRangeList}). Range
 * lists are objects containing arrays of {@link SVNMergeRange ranges}
 * describing the ranges which have been merged into <code>target</code>'s URL (working copy path) as of
 * <code>target</code>'s <code>pegRevision</code>. If there is no mergeinfo, returns <code>null</code>.
 * <code>Target</code> can be either URL or working copy path.
 * 
 * <p/>
 * Note: unlike most APIs which deal with mergeinfo, this one returns data
 * where the keys of the map are absolute repository URLs rather than
 * repository filesystem paths.
 * 
 * <p/>
 * Note: this routine requires repository access.
 * 
 * {@link #run()} throws {@link org.tmatesoft.svn.core.SVNException} in the following cases:
 *             <ul>
 *             <li/>exception with {@link SVNErrorCode#UNSUPPORTED_FEATURE}
 *             error code - if the server doesn't support retrieval of
 *             mergeinfo (which will never happen for file:// URLs)
 *             </ul>
