bug#59221: (file-exists? #f) raises an exception

[Joshua Branson]

Hello you lovely guile people!

This bug is so simple the subject line says it all!

file-exists? is a predicate, but

#+BEGIN_SRC scheme
(file-exists? #f)
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure stat: Wrong type argument in position 1 (expecting open file 
port): #f

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
#+END_SRC

I will shortly tag this as "easy".  Can you lovely maintainers give me
about a week to try to fix this myself?

Thanks,

Joshua
