"""A question with a name in it is asked by confirm.js, never by a handler.

An inline handler such as `onclick="return confirm('Disabling {{ u.name }}…')"`
puts the name inside a script, so an apostrophe, as in "Jo's portfolio",
broke the handler and the question silently never appeared. In
`data-confirm` the words are an attribute, and only ever text
(test_confirm_in_the_browser.py checks it in a browser).
