//
// Tweak to make a double-click select words with hyphens or
// apostrophes.
//
// As of 2023-04-12, None of the major browsers selects whole
// words with hyphens, like "ad-lib". Only the text before or
// after the hyphen, or the hyphen on its own, will be selected.
// This tweak fixes the hypen issue.
//
// Note: Firefox (at least until version 111.0.1) also doesn't
// automatically select whole words with apostrophes like the word
// "doesn't".
//
// In Safari (at least until version 16.3), a double-click that
// lands precisely on an apostrophe will select only the
// apostrophe. However, a double-click on any *letter* in a word
// that contains an apostrophe will select the entire word,
// including the apostrophe.
//
// This tweak also treats these issues.
// On Windows, a double-click on a word will also select the space
// after the word, if there is one. On MacOS and Ubuntu, only the
// word itself is selected. This tweak respects these
// platform-specific differences.
// In the comments below, I'll use the word "join" to mean any of
// the following hyphen and apostrophe characters:
//
// * - (hyphen: ‐)
// * ‑ (non‑breaking hypen: &8209;)
// * ­ (soft hyphen, which only appears at a line break)
// * ' (apostrophe: ')
// * ’ (right single quotation mark: ’).
//
// NOTE 1: It is not trivial to distinguish between a final
// apostrophe, which is an integral part of a word, that is used
// to indicate possession)...
//
// She said, "Those books are Jodi's, but these are my kids'".
//
// ... from a closing single quote:
//
// He said, "She said, 'Meet Jo and Di. These are my kids'".
//
// For simplicity, this script ignores both cases. As of 2023-04-12,
// all major browsers behave in exactly the same way.
//
// NOTE 2: Two hyphens can be used to indicate a dash—a character
// which indicates a secondary thought–and some writers leave no
// spaces around a dash. However it is never used to make compound
// words. "Two consecutive hypens should be ignored--at least I
// think they should."
