... for strings beginning with a '/', obviously, not for all patterns.
Which is broken for aliases and shell functions:

torch% /foo() { print Look, I have a slash. }
torch% whence -v /foo
/foo is a shell function
torch% whence -mv '/fo?'	# won't work with the above change
/foo is a shell function

PWS's change for -a only works because it happens so late in the algorithm
that there is nothing left but path to search, and no patterns left to be
tried.
