Store is undeletable if store name is accidentally ended with /

[p4perf4ce]

Summary

Accidentally created a new store with --store name/ instead of --store name making it undiscoverable by gopass. This will require the user to manually delete the mount point in the config file.

Steps To Reproduce

1. Initialize the password-store with [a-zA-Z]+\/
2. gopass ls will show the mount as STORE_NAME without / but you can't do anything with it. Note that the actual path / is replaced with -. E.g., /home/username/.local/share/gopass/STORE_NAME-

Expected behavior

If the name is illegal, it shouldn't be created.

Environment

Additional context

Remove the things in .config/gopass/config can workaround this issue.

Good point. Indeed. This is clearly missing some input validation. We'll add that.
