I would like to include a null string as part of a parameter expansion word:
mapfile -t${bNullDelimited+d ''}
When bNullDelimited is set, I expect this to expand to:
mapfile -td ''
However, it expands to:
mapfile -td
Note that a lone null string is successfully expanded:
mapfile -t${bNullDelimited+d} ${bNullDelimited+''}
The bash gurus in my neck of the woods consider this behavior unexpected.\ Is it a bug?
