Only one bad example for now, which is a misspelling that's not
entirely uncommon and can lead to real problems (see linked bug).

Example output:
Line 58: 'my_new': Misspelled <string> attribute.
        Actual: translateable
        Example: translatable

Expand strings into samples that are representative of what'll be
shown in UI, and warn if they're longer than defined CHAR LIMIT.

Guide all-caps strings towards android:textAllCaps if actions.

Warn when strings mention "phone" without defining product-specific
variants.

Strings are tedious to get right, so write a lint script that catches
common errors to warn developers before they're uploaded.
