There are some contexts, such as variable assignments, where double quotes
are not necessary.
foo='a b'
bar=$foo
is just as safe as
bar="$foo"
In fact, it is MORE portable to avoid double quotes in assignments, if you
are worried about writing scripts portable to more than just bash. Of
these two constructs:
foo="`echo "a b"`"
bar=`echo "a b"`
only the setting of bar is guaranteed to parse correctly in all shells.
