printpathn is designed for printing paths, and paths cannot be longer than MAXPATHLEN. Longer arguments would result to ENAMETOOLONG anyway, so there is no need to print more than MAXPATHLEN. I think we should follow this scheme no matter whether relative paths are converted to absolute or not: if the path "passed" to printpathn is longer, ellipsis should be added. -- ldv
