Comment (by miqrogroove):

 Yes, there is an unfortunate bug in shortcodes.php.  If we want to write
 something like this ...

 {{{The proper way to end the caption is with the [[/caption]] tag.}}}

 ... the "escaped" tag is ignored by the shortcode engine and the output is
 not unescaped as expected.  As a result, the input is required to be
 unescaped by the user ...

 {{{The proper way to end the caption is with the [/caption] tag.}}}

 ... to get the correct output, whereas the syntax changes again with tag
 pairs ...

 {{{The caption code is [[caption] like this [/caption]].}}}

 I think I can accommodate this by adjusting the unit tests and tweaking
 one or two conditions.  The regexp should still work because it is not
 checking the symmetry of extra braces.
