Shorthand.el

Simple-minded namespacing in Emacs:

1. Do this on an Emacs you don't care about, since this advises basic functions;
2. Load shorthand.el (or byte-compile and load it);
3. Load magnar-string.el or byte-compile it and load magnar-string.elc;
4. Try C-h f and check there's no "s-" pollution; Not even the s- symbols are interned;
5. Check that all the functions are namespaced under "magnar-string-";
6. Open test.el, and play around there. Open test2.el and play around with magnar-string.el under a different "mstring-" prefix;
7. Evaluating code should work. Eldoc should also work. Xref (M-.) is broken. Anything else might breaks spectacularly;

Under the hood

Read shorthand.el: it's less than 50 loc. The idea is to keep only one obarray, but instruments read to not pollute it with symbols that with the shorthands for other longer named symbols.
