This change better resembles the output generated by `Snapshot.String()`,
which includes both username and hostname.

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".
Since Go 1.21, most reparse points are considered as irregular files.
Depending on the underlying driver these can exhibit nearly arbitrary
behavior. When encountering such a file, restic returned an
indecipherable error message: `error: invalid node type ""`.
Add the filepath to the error message and state that the file type is
not supported.
Adds
* snapshotMetadataArgs, which holds the new metadata as strings parsed from
the command line
* snapshotMetadata, which holds the new metadata converted to the
correct types
Bug #1681 suggests that restic should not be nice to user and should
refrain from creating a mountpoint if it does not exist. Nevertheless,
it currently opens the repository before checking for the mountpoint's
existence. In the case of large or remote repositories, this process
can be time-consuming, delaying the inevitable outcome.
/restic mount --repo=REMOTE --verbose /tmp/backup
repository 33f14e42 opened (version 2, compression level max)
[0:38] 100.00% 162 / 162 index files loaded
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory
real 0m39.534s
user 1m53.961s
sys 0m3.044s
In this scenario, 40 seconds could have been saved if the nonexistence
of the path had been verified beforehand.
This patch relocates the mountpoint check to the beginning of the
runMount function, preceding the opening of the repository.
