Unpaired ``` not gracefully handled

[bethcutler]

Original code; triple quote is unpaired accidentally

/**
 * ```kotlin
 * class foo {
 * }
 */

After formatting; an even # of triple quotes are added, which does nothing to solve the problem. Every time formatter is run, more triple quotes are added.

/**
 * ```kotlin
 * ```
 * ```
 * class foo { }
 * ```
 * ```
 */

Here's a similar example, in which the triple quotes are not unpaired:

Before:

  /**
   * Title ```block```.
   * More text.
   */

After formatting once:

  /**
   * Title ```block```.
   * ```
   * ```
   * More text.
   * ```
   * ```
   */

Each time the file is formatted, 2 more lines of triple quotes are added before and after.

I started looking into this, and it looks like the problem stems from kdoc lexer tagging whatever token follows "block." as a CODE_BLOCK_TEXT token, which I would assume is a bug.

Not sure if we can fix kdoc lexer. But also not sure what an appropriate workaround would be.

Update: the first issue is indeed fixed, but the second case is still not ideal.

Original:

/**
 * Title ```block```.
 * More text.
 */

Formatted:

/**
 * Title
 * ```block```.
 * More text.
 * ```
 */

Adding a new triple quote seems wrong in this case. That said, this is likely a poor usage of Markdown where single backticks would be better.

Just ran into this today as well, happy to share more repro cases

[hick209]

v0.49 formats

/**
 * Title ```block```.
 * More text.
 */

to this:

/** Title ```block```. More text. */

Which seems to me like the issue has been fixed.
