Subject: If the continuation of a combination is always known, do not record it
X-Git-Tag: 20090517-FFI~12538
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=0c650ac91738cc77c62f872cd7acfe705e6067be;p=mit-scheme.git

If the continuation of a combination is always known, do not record it
as the invocation continuation.  This is because the object will not
exist, and thus its label will never be defined.
