Bug #4437: Hash does not match character read from file via IO#getc

Run this little program, and observe that the single-character read from a file does not match a hash key as it should.

===========================================
# Create a file with the single character 'x', then read it back into var x.
open('x', 'w') {|f| f.write('x')}
x = open('x') {|f| f.getc}

# Create a Hash with x as a key.
h = {'x' => 'xx'}

# Retrieve the value, to show that the hash (of course) works with ordinary
# characters.
p 'h["x"] =>', h["x"]
p 'h[?x] =>', h[?x]

# Retrieve the value using the 'x' obtained using getc, showing that the
# hash match fails for the same character as retrieved from a file.
puts
p 'x =>', x
p 'h[x] =>', h[x]
======================================================
