To illustrate the previous behavior, consider these tags and their start
and end positions (shown inclusively below):
Start tag: End tag:
<span> </span>
^ start ^ start
^end ^end
The start position of a tag is the first ASCII-alpha code point after
the opening brace. The start position of a close tag is the slash just
before the first ASCII-alpha code point. And the end position of both
is the closing brace. So the opening brace is not included in the
emitted tag, but the closing brace is. And the end tag including the
slash is an oddity that had to be worked around in its only use case
(syntax highlighting).
We now consistently exclude the braces from the emitted tag, and also
exclude the slash from the end tag, so that it does not need to be
accounted for in syntax highlighting. That is, we now have:
Start tag: End tag:
<span> </span>
^ start ^ start
^end ^end
The tokenizer unit test has been extended to test these positions.
