Text to go in the release notes:
The patron category type code (A, C, O, ...) is currently displayed in the patron module search, patron card creator, and acquisition patron searches.
This information is not useful for most users, as these are internal codes that cannot be easily "decoded". And while you might be able to guess A as Adult in English, it doesn't translate to other languages.
This patch wraps a span around the patron category type code shown in () after the patron category.
