Space in path on Linux causes error message when restoring on Windows

Output of restic version

restic 0.19.1 compiled with go1.26.4 on windows/amd64 (Windows) restic 0.18.1 compiled with go1.25.0 on linux/amd64 (Linux)

What backend/service did you use to store the repository?

My VPS, running Ubuntu 26. So the backup and restore commands looked like: "restic -r sftp:my_name@my_vps.com:/path-to-repo backup ." "restic -r sftp:my_name@my_vps.com:/path-to-repo restore latest --target ."

Problem description / Steps to reproduce

I performed a "backup" command on Linux, to backup some files. One directory in the backup data accidentally had a space at the end of the directory name - e.g.

data/dir-a/aaa.txt
data/dir-b /bbb.txt <- note the space
data/dir-c/ccc.txt

The backup completed with no errors.

I then restored that snapshot on Windows. The backup reported errors: "Unable to set timestamp of file data\dir-b\bbb.txt - no such file or directory" All files were restored. The 'dir-b' did not have a space at the end (which I think Windows forbids anyway).

I went back to Linux, removed the space, and did a new backup snapshot. The new snapshot restored on Windows without errors.

Expected behavior

Not sure :) Maybe warn about spaces at the end of path components on Linux? Or a more meaningful error message on Windows.

Actual behavior

See above
