Possible typo in Django's documentation

[i.amber.jain@…]

​https://docs.djangoproject.com/en/1.5/topics/db/models/#field-options lists following example (under "choices" sub-section):

from django.db import models

class Person(models.Model):
    SHIRT_SIZES = (
        ('S', 'Small'),
        ('M', 'Medium'),
        ('L', 'Large'),
    )
    name = models.CharField(max_length=60)
    shirt_size = models.CharField(max_length=2, choices=SHIRT_SIZES)

Why does the example below has max_length=2 instead of max_length=1 ? Is this because of some DB/vendor issue (I could not find anything about this at ​https://docs.djangoproject.com/en/1.5/ref/databases/)?
Someone on #django (freenode) suggested this could be a typo. So, I thought of reporting it here.

Thanks!
