gh-151819: Clarify the conditional-pattern email example in re docs (GH-153072)
The example pattern does not fail to match '<[email protected]' outright -- re.search finds '[email protected]' in it; it only fails to match the whole string. Reword to say so. Co-authored-by: Claude Opus 4.8 <[email protected]>
