Avoid adding real names when the user is using a real name

[fregante]

This isn't useful:

I'd rather see this:

---

Feature: show-names

If name matches username
	replace username with name (to keep capitalization)

• Either we drop the space altogether (so in this case there won't be any changes for these users, but there would be for sindresorhus, which would become SindreSorhus), or
• we replace it with <span style="margin-left:0.2em"/> so it won't break copy-pasting.

Example URL:
microsoft/TypeScript#30442 (reference)

Wouldn't this break #2146, in a way 🤷‍♂️.

[sindresorhus]

Sounds good, but there should be a space visually, I don't want to see SindreSorhus.

[fregante]

Wouldn't this break #2146

As far as textContent is concerned, only the case will change. sindresorhus -> SindreSorhus so to fix that feature we just need a .toLowercase() in a couple of places.

---

To make it even safer if could use

<u>s</u>indre<s/><u>s</u>orhus

where s and u are margin-left: 0.2em and text-transform: uppercase respectively.

.textContent would be completely unchanged for all extensions, however it's probably a pain to code that.

Or use .pathname to get the user name instead of .textContent

One more: Punctuation.
