The reason for anchoring is to reduce surprising behavior.  Especially
since this only replaces one occurance, it seems like the path of least
astonishment.  For instance, "substitute-path foo bar" would replace
/fool with /barl and /tmp/myfoo with /tmp/mybar.

I'd much prefer (1); I'm ambivalent on (2); whatever anyone prefers is
fine.
