[Doc-SIG] bdb.Bdb.canonic() -- What "stripped of surrounding angle brackets" means?

[INADA Naoki]

Hi, all.

on http://docs.python.org/library/bdb.html

  canonic(filename)
  Auxiliary method for getting a filename in a canonical form, that
is, as a case-normalized
  (on case-insensitive filesystems) absolute path, stripped of
surrounding angle brackets.

Is " stripped of surrounding angle brackets." means it removes "<" on
left end and ">" on right end?
In the code:

    def canonic(self, filename):
        if filename == "<" + filename[1:-1] + ">":
            return filename
        canonic = self.fncache.get(filename)
        if not canonic:
            canonic = os.path.abspath(filename)
            canonic = os.path.normcase(canonic)
            self.fncache[filename] = canonic
        return canonic

canonic() doesn't remove "<" and ">".
