 In [changeset:"33648"]:
 {{{
 #!CommitTicketReference repository="" revision="33648"
 Upgrades: When upgrading via FTP, use `LIST -a` to detect if a file
 exists.
 `LIST` & `NLST` by default on some servers require the `-a` flag to view
 hidden files (ie. `.maintenance`)
 Although we could simply pass the `-a` flag to `NLST`, opting to use
 `LIST` which we use elsewhere should mean less chance of server
 incompatibilities.

 Props jcroucher.
 Fixes #28013.
