Enhancement: Add bitrot detection to `diff` command

The output of the `diff` command now includes the modifier `?` for files
to indicate bitrot in backed up files. It will appear whenever there is a
difference in content while the metadata is exactly the same. Since files with
unchanged metadata are normally not read again when creating a backup, the
detection is only effective if the right-hand side of the diff has been created
with "backup --force".

Add bitrot detection to "diff" command This introduces a new modifier to the output of the diff command. It appears whenever two files being compared only differ in their content but not in their metadata. As far as we know, under normal circumstances, this should only ever happen if some kind of bitrot has happened in the source file. The prerequisite for this detection to work is that the right-side snapshot of the comparison has been created with "backup --force". 2023-10-20 18:15:53 +00:00			Enhancement: Add bitrot detection to `diff` command
