Subject: [PATCH] aider: Added error message when no files matched in cmd_add
 and cmd_drop.

# Context:
USER: in cmd_add and cmd_drop, print an error if no files matched
ASSISTANT: To print an error message when no files are matched in `cmd_add` and `cmd_drop`, you can add a check for the length of `matched_files` and print an error message if it's zero. Here are the changes:

```python
aider/coder.py
<<<<<<< ORIGINAL
    def cmd_add(self, args):
        "Add matching files to the chat"

        files = self.get_active_files()
        for word in args.split():
            matched_files = [file for file in files if word in file]
=======
    def cmd_add(self, args):
        "Add matching files to the chat"

        files = self.get_active_files()
        for word in args.split():
            matched_files = [file for file in files if word in file]
            if not matched_files:
                self.console.print(f"[red]No files matched '{word}'")
>>>>>>> UPDATED

aider/coder.py
<<<<<<< ORIGINAL
    def cmd_drop(self, args):
        "Remove matching files from the chat"

        for word in args.split():
            matched_files = [file for file in self.fnames if word in os.path.relpath(file, self.root)]
=======
    def cmd_drop(self, args):
        "Remove matching files from the chat"

        for word in args.split():
            matched_files = [file for file in self.fnames if word in os.path.relpath(file, self.root)]
            if not matched_files:
                self.console.print(f"[red]No files matched '{word}'")
>>>>>>> UPDATED
```
