pub const ATTACHMENT_DELETE: &str = "\
Remove an attachment from an issue.
```
ytcli attachment list PROJ-1
ytcli attachment delete PROJ-1 1234 --yes
```
`--yes` even for one file: Tracker keeps no copy, and whatever pointed at it —
a comment, the description — is left pointing at nothing. The name of the file
is printed before it goes, because an attachment id says nothing about what it
is; `attachment list` is where the ids come from.
Uploading is not undone by this so much as followed by it: the change is in the
issue history either way, and everyone who already downloaded the file still
has it.";
