I'm interested to find 29 instances of "if and only if" in the source,

Please find attached a mechanically done patch which expands the

"iff" is well-known abbreviation, I don't see a need to expunge it from
the source code. There might be places where some other wording or
spelling it out as "if and only if" would be better, but a mechanical
search/replace is not warranted.
FWIW, many other languages use a similar abbreviation for the same
thing, so it's not impossible for a non-native English speaker with
basic math education to guess. In Finnish, it's "joss", which stands for
"jos ja vain jos", and a quick look at Wikipedia shows a similar
construct in many other languages.
