Is there any way to make it local? If I make composition-function-table 
buffer-local and set the buffer-local variable, would it work? The 
use-case I'm thinking about is using Commit Mono for Info buffers and 
help buffers, which have large bodies of monospaced text. The improved 
readability would help a lot there.
