Be more careful to maintain quoting information when parsing commands.

This is particularly a problem for alias construction, where you might
want to have a backtick surrounded option in the alias.  Before this
patch:

command alias expression -Z \`argc\` -- argv

for instance would be rendered as:

expression -Z argc -- argv

and would fail to work.
