Chris Schanzle mentioned off-list that a tab character had been replaced with spaces (I *knew* that should have been an attached file, shame on me). He also suggested an improvement that removes the tab character, so here's a second try.
Or not? Last try.
#!/bin/sh
declare -a cmdline
tab=$'\t'
eol=$'\n'
for arg in "$@"
do
arg="${arg//\\011/$tab}"
arg="${arg//\\012/$eol}"
arg="${arg//\\040/ }"
arg="${arg//\\134/\\}"
arg="${arg//\\\\/\\}"
cmdline+=("$arg")

The problem there is that the last line is going to get interpreted by a shell before anything is executed, so you now have to escape characters that are special to the shell within a quoted string. This is unlike the compiled fstab-decode program that invokes the execvp() library call and avoids further shell parsing.
