fix potential data loss The help option for jdupes says: -d --delete: prompt user for files to preserve and delete all others; [...] . Using the command 'jdupes -d .', a prompt will appear: Set 1 of 1: keep which files? (1 - 5, [a]ll, [n]one, [l]ink all, [s]ymlink all): It is a mistake to set 2-4 because the jdupes considers one file only. Setting '2-4', the file 2 will be kept and the files 3 and 4 will be deleted. The sentence 'keep which files? (1 - 5' induces the users to use a range and it is not valid. Currently, jdupes is not denying this behaviour and it is generating a data loss. . This patch fixes this issue. ===================================================================
