Argument metavar parameter not used with exception message

[rsyring]

The Code

@app.command('mssql', short_help='Backup Microsoft SQL database(s).')
@click.argument('backup_type', metavar='type')
def mssql(backup_type):
    click.echo('Running the backup...')

Expected Output

(backupdb)rsyring@loftex:~/projects/backup-db-src$ backupdb mssql
Usage: backupdb mssql [OPTIONS] type

Error: Missing argument "type".

Actual Output

Note that the metavar parameter is used in "Usage" but not when notifying the user about the missing argument:

(backupdb)rsyring@loftex:~/projects/backup-db-src$ backupdb mssql
Usage: backupdb mssql [OPTIONS] type

Error: Missing argument "backup_type".

Thanks for the fix. I saw your post on joining Sentry. I hope that allows you to work more in the OSS world, I really appreciate a lot of the projects you put out. Will also be checking out Sentry, I've been looking for something like that.
