When 'foldmethod' is set to "syntax", blocks of code and multi-line comments
will be folded. No text is usually written in the first line of a multi-line
comment, making folded contents of Javadoc comments less informative with the
default 'foldtext' value; you may opt for showing the contents of a second
line for any comments written in this way, and showing the contents of a first
line otherwise, with >
