The behavior of this function is quite counter-intuitive, as it preserves the delimiter in the result. This function should probably have been an internal function, as its use for external consumers would be very limited, but let's at least document the (surprising) behavior for those that are considering to use it. It appears that BuildKit is currently the only (publicly visible) external consumer of this function; I am planning to inline its functionality in Spec.Digest() and to deprecate this function so that it can be removed.

Inline the relevant code from SplitObject, as we're only interested in the digest portion. Signed-off-by: Sebastiaan van Stijn <[email protected]> (cherry picked from commit a5fce38) Signed-off-by: Sebastiaan van Stijn <[email protected]>
