Subject:   As suggested by Josh Slive, add the explicit 'default' to AcceptPathInfo.
X-Git-Tag: 2.0.30~209
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=97ff8a3f1f8c00ba219885b3b0b9744084eef647;p=apache

  As suggested by Josh Slive, add the explicit 'default' to AcceptPathInfo.
  I'll leave docs up to him.  The conf becomes a quadstate (undef != default)
  but other than that, it should make things cleaner for the user.
