Asterisk without trailing whitespace in block comment is not stripped

[sgrekhov]

According to the Dart doc specification

Any whitespace immediately following the asterisk is also stripped, if present.

The phrase “if present” assumes that the whitespace may be absent. In case

/**Text.
 *More text.
 */

The expected output is

Text.
More text.

In fact, the asterisk became part of the comment.

Expected: 'Text.\n'
            'More text.'
  Actual: 'Text.\n'
            ' *More text.'

See https://github.com/dart-lang/dartdoc/blob/main/test/co19/block_based_doc_comments_test.dart, the tests test_contentNoTrailingWhitespace1() and test_contentNoTrailingWhitespace2().

I thing it's the same issue.

/***Line 1.
 **Line 2.
 **/

Output:

Expected: '*Line 1.\n'
            '*Line 2.\n'
            '*'
  Actual: 'Line 1.\n'
            ' **Line 2.\n'
            ' *'
