Tangentially to -workers:  Is _canonical_paths documented in the wrong
manual section?  It's lumped in with functions that are expected to
appear in the "completer" zstyle, which clearly it is not.

I'm not able to reproduce this using nothing but compinit plus the
compdef above.  I get just one completion, "/tmp/My\ File", regardless
of whether that file exists or not.

Try this:

debug_canonical_paths () {
  _canonical_paths -N files files /tmp/My\ File
}
compdef '_complete_debug debug_canonical_paths' cmd

Pressing TAB then drops a file in /tmp with a debug trace of the
execution of _canonical_paths.  In particular look at which "zstyle"
lookups are being done and which of those might be causing the extra
entries.  You can also look at the context around elements being added
to the "matches" array.
