Are you quite sure? I just tried the same thing, and didn't find any
spaces between the number and the word "total". What I did find was
a tab:

username@hostname$ du -c dtd
84	dtd
84	total
username@hostname$ du -c dtd | sed 's/ /s/g'
84	dtd
84	total
username@hostname$ du -c dtd | sed 's/\t/tab/g'
84tabdtd
84tabtotal
username@hostname$

Nope, tabs are much better for column alignment than are spaces. They
yield, one might say, a "tabular" format.
