uploaded 37_tilde_ok.0.8.15.patch

["Roy T. Fielding" <fi...@avron.ICS.UCI.EDU>]

One of the earlier releases that I didn't test on my server changed
the handling of patch escapes such that all FancyIndex URL paths
are escaped.  Unfortunately, Apache uses the "~" character for default
user directory prefixes.  The result is that Apache 0.8.15 is changing
the URL from /~user to /%7euser in a rather arbitrary fashion.
This is bad, even though it may be considered as being RFC 1738 compliant,
since we (the authors of the URL specs) are planning on including tilde
in the allowed character set anyway the next time the specs are revised.

In any case, it is guaranteed to cause users to complain and muck up
a browser's history file.

This is 37_tilde_ok.0.8.15.patch:

From: Roy Fielding <fi...@ics.uci.edu>
Subject: Changes path escaping to allow the tilde "~" character in paths.
Affects: util.c
ChangeLog: Do not escape tilde "~" character during the creation of
           FancyIndexes
Comments: Yes, I know it isn't strictly according to RFC 1738, but that
          document is overly restrictive (i.e., wrong) in that regard
          and will be changed in the next revision.
