Would the recently added file-subdir-of-p be more appropriate?

Also, I'd never heard of string-prefix-p (added in 23.2). It was never
mentioned in NEWS or documented in the manual.

It also exists as vc-string-prefix-p, latex-string-prefix-p,
tex-string-prefix-p, cvs-string-prefix-p, mpc-string-prefix-p...
