lines with leading hashes in multiline string treated like comment

[markkap]

something like
key = """
#I am here
"""

will have an empty string for key instead of "#I am here". Supporting this is not explicitly mention in the spec examples, but follows the spirit of using hashed in a one line string

after playing a little with the code it seems like line 400 should be
' elseif($toml[$i] == '#' && !$openString && !$openKeygroup && !$openMString && !$openMLString)'
