Thanks!  This seems to be working very well.

Unfortunately, there is one small problem: editing inside an identifier
name becomes a little sluggish: if you go down to `x_initialize' (in
xterm.c), type "int", TAB, and hold down "ddddddddddddddddddddddd" on
any line, you will see Emacs slow down to a crawl.

That seems to only be a problem in big files, however.
