vim: Saving a file that has xattrs resets the xattrs

[pjotrek-b]

Saving a file with vim (8.1.1847, Xubuntu 20.04) that has xattrs set, resets its xattrs:

1. touch aha
2. setfattr -n user.pb -v "aha works" aha
3. alias gx='getfattr -d -m - '
4. gx * # show attributes
5. vim aha (then :wq save and exit)
6. gx * # shows no more attributes

Attributes are gone. 😭

This is how things are like /RIGHT NOW/ - where xattrs are not properly cared for in the user/tool landscape.
This does not have to stay like that in the future.
