Bug 23251: Correct formatting of IMD data ending in apostrophe

IMD text data may end in an apostrophe (e.g. dreamin' )
This was causing the segment to be incorrectly formatted
as only the last character was checked, not the preceding
character to check whether it was quoted

add a test for this specific occurence
