    Bug#39559: dump of stored procedures / functions with C-style \ · 8c828507

    	comment can't be read back
    
    A change to the lexer in 5.1 caused slash-asterisk-bang-version
    sections to be terminated early if there exists a slash-asterisk-
    style comment inside it.  Nesting comments is usually illegal,
    but we rely on versioned comment blocks in mysqldump, and the
    contents of those sections must be allowed to have comments.
    
    The problem was that when encountering open-comment tokens and
    consuming -or- passing through the contents, the "in_comment"
    state at the end was clobbered with the not-in-a-comment value,
    regardless of whether we were in a comment before this or not.  
    
    So, """/*!VER one /* two */ three */""" would lose its in-comment
    state between "two" and "three".  Save the echo and in-comment
    state, and restore it at the end of the comment if we consume a 
    comment.
