I tried to make the synopsis a little less theoretical with the placeholders and instead introduced the actual scope options, long and short once, then refer to them as -Uflg from then on. I mentioned that list indicies are accepted / work to erase stuff. In the list of options, we pretend like --unexport is long-only. Especially with --unpath and --path, and what would go wrong if one confused it with --univeral, and how rarely it's used, I think it's better this way. I mention it as a synonym later in the document so that it's not literally undocumented. Changed phrasing such as: "Causes the specified shell variable to be given a global scope" Which can be read as we are taking a shell variable that exists and giving it global scope, upgrading it to global (retaining the value). Redid the example section using the > syntax for things entered into a prompt, with shell output following. The explanatory Added in missing newlines at the ends of sentences.
