A number of expressions are possible to represent a
plist. For instance, we can use the form <tt>(K1:V1, K2:V2,
-... ,Kn:Vn)</tt> to represent a plist whose first property key and
+..., Kn:Vn)</tt> to represent a plist whose first property key and
value are K1 and V1, second key and value are K2 and V2, and so on.
However, we can use a simpler expression here because the types of
plists used in the m17n database are fairly restricted.
An element that matches the regular expression
<tt>[^-0-9(]([^\\()]|\\.)+</tt> represents a property whose key is
-<tt> Msymbol</tt>. In the element, <tt>\\t</tt> , <tt>\\n</tt>,
+<tt> Msymbol</tt>. In the element, <tt>\\t</tt>, <tt>\\n</tt>,
<tt>\\r</tt>, and <tt>\\e</tt> are replaced with tab (code 9), newline
(code 10), carriage return (code 13), and escape (code 27)
respectively. Other characters following a backslash is interpreted
