Maybe. After reading a bit about xargs, here's an alternate way using
only sed:
manpath | sed -e 's/ /\\ /g' -e 's/:/ /g' | xargs -0 ls
First you escape any spaces in the input, then you replace : with
space. If you have even weirder pathnames, like ones with quotes or
backslashes in them, you can use this:
sed -e 's/\([^:]\)/\\\1/g' -e 's/:/ /g'
which will backslash-escape everything except colons.
