Replace spaces in inline code with non-breaking spaces

  *  For unordered lists, use asterisk, at least for the first level.
 
- *  Optimal spacing is 1 space, asterisk, 2 spaces, e.g. ` *  foo`.
+ *  Optimal spacing is 1 space, asterisk, 2 spaces, e.g. ` *  foo`.
 
  *  For ordered lists, optimal spacing is one or zero spaces in front
-    of the number, then one space, e.g. ` 9. Foo`, then `10. Bar`.
+    of the number, then one space, e.g. ` 9. Foo`, then `10. Bar`.
 
 
 Jargon names

  *  Use reference-style, i.e. `[link text][1]` and then, after paragraph
-    (or later if that makes sense), use `  [1]: http://www.foo.../`.
+    (or later if that makes sense), use `  [1]: http://www.foo.../`.
 
  *  Note that you don't need to use numbers: keyword is OK (even spaced),
     but *keep it consistent within the document*.
 
  *  You can also use `[link][]`; here the keyword = link text (i.e.
-    `  [link]: http://whatever` would follow).
+    `  [link]: http://whatever` would follow).
 
  *  Links can be local (although I have only used this in Github).
