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.
Does it, though?
$ bash fstab-decode.sh echo '$PATH'
$PATH
$ bash fstab-decode.sh ls '*'
ls: cannot access '*': No such file or directory
After study, the only types of expansion that occur _after_ parameter expansion
are word splitting and pathname expansion, and those are both protected by the
double quotes. So, I guess it's OK.
