If you ever want to change the title and descriptions associated with
a patch and its revisions, we can always use the `rad patch edit`
command.

First off, we'll have to set up a patch and an updated revision:

```
$ git checkout -b changes
$ touch README.md
$ git add README.md
$ git commit --message "Add README, just for the fun"
[changes 03c02af] Add README, just for the fun
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 README.md
```

``` (stderr)
$ git push rad -o patch.message="Add README, just for the fun" HEAD:refs/patches
✓ Patch 89f7afb1511b976482b21f6b2f39aef7f4fb88a2 opened

```

```
$ touch LICENSE
$ git add LICENSE
$ git commit -v -m "Define the LICENSE"
[changes 8945f61] Define the LICENSE
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 LICENSE

``` (stderr)
$ git push -f -o patch.message="Add License"

```

Let's look at the patch, to see what it looks like before editing it:

```
$ rad patch show 89f7afb

```

We can change the title and description of the patch itself by using a
multi-line message (using two `--message` options here):

```
$ rad patch edit 89f7afb --message "Add Metadata" --message "Add README & LICENSE" --no-announce
$ rad patch show 89f7afb
╭────────────────────────────────────────────────────╮
│ Title     Add Metadata                             │

```

Notice that the `Title` is now `Add Metadata`, and the patch now has a
description `Add README & LICENSE`.

If we want to change a specific revision's description, we can use the
`--revision` option:

```
$ rad patch edit 89f7afb --revision 5d78dd5 --message "Changes: Adds LICENSE file" --no-announce
$ rad patch show 89f7afb
╭────────────────────────────────────────────────────╮
│ Title     Add Metadata                             │

│ Author    alice (you)                              │

│ Branches  changes                                  │
│ Commits   ahead 2, behind 0                        │
│ Status    open                                     │
│                                                    │
│ Add README & LICENSE                               │
├────────────────────────────────────────────────────┤
│ 8945f61 Define the LICENSE                         │
│ 03c02af Add README, just for the fun               │
├────────────────────────────────────────────────────┤
│ ● Revision 89f7afb @ 03c02af by alice (you) now    │
│ ↑ Revision 5d78dd5 @ 8945f61 by alice (you) now    │
╰────────────────────────────────────────────────────╯
```

We can see that this didn't affect the patch's description, but
currently there's no way of seeing a revision's description in the
CLI.
