no tag to specify how to handle mutltiple, repeated delimiters
There is nothing in eml to say whether multiple repeated delimiters should be
treated as a single delimited. An example is when a space delimiter is used;
often there may be several repeated spaces that should be treated a a single
delimiter, but not always. Need a boolean to say whether sequential delimiters
should be treated as a single delimiter or not.
In Morpho 1.5 this information was placed in addedMetadata.
