Empty commented line in inline comments leads to error

[jkraskesis]

Inserting an empty commented line in inline comments leads to error:
/**

• @startuml
• Alice->Bob : hello
• Bob --> Alice : hello to you too
• @enduml
  */
  leads to
  [From string (line 3) ]
  @startuml
  Alice->Bob : hello
  *
  ^^^^^
  Syntax Error?

It would be nice if this was permitted as many editors automatically insert a '*' when adding an extra line in a comment and "blank" lines are helpfull in structuring large inline plantuml cpmments

The YAML support in PlantUML, forced med to handle whitespace differently, since YAML is whitespace-sensitive. Here I take the prefix before @startuml and remove it from the other lines if it's there. In this case the prefix is " * ", so a line with only " *" will not end up as the empty line, at least this is the intention. If the line really consists of " * " and not " *", my implementation must be faulty. I could also add logic for detecting the case where a trimmed prefix equals a trimmed line and remove that line.
