My thoughts entirely about the need for two apostrophes in DH or none at all. I think everyone would agree it would look ridiculous with two. Consider longer acronyms too - for example, G'N'H'Q'
.
There is a similar debate regarding decades: 90s or 90's? I cannot for the life of me see what the apostrophe is for and yet it is the example without the apostrophe that spell check has underlined. If anything, there should be one at the beginning, to indicate omission of '19'. For my money it should be '90s, but again, spell check disagrees with me. (Though I do realise that spell check is probably American and can therefore be disregarded
)
