Actually, there was something about Linedit that I hated: it would print a Unicode
"bell" emoji instead of beeping the shell's bell (which I also hate and disable).
So I went into the code and patched it, commenting out the stupid beeping.

$ diff -u quicklisp/dists/quicklisp/software/linedit-20150709-git/terminal.lisp~ quicklisp/dists/quicklisp/software/linedit-20150709-git/terminal.lisp

Now the SBCL command line has excellent tab completion, and is silent, as shells should be.
