      Two minor enhancements to mod_rewrite: First RewriteRule now also supports the · 75bb8d07
      Ralf S. Engelschall authored 
      ``nocase|NC'' flag (as RewriteCond already does for ages) to match case
insensitive (this especially avoids nasty patterns like `[tT][eE][sS][tT]').
Second two additional internal map functions `escape' and `unescape' were
added which can be used to escape/unescape to/from hex-encodings in URLs parts
(this is especially useful in combination with map lookups).

      ``Oh, by the way: the same procedure as last year? · 3fae2252

        The same procedure as _every_ year, James!''

So, a lot of touched files here, but it's just a tiny harmless patch.
As every year we bump up the year number in our copyright headers.

1. "199x-1998" => "199x-1999"
2. "1998"      => "1998-1999"

      Fix a few minor inconsistencies related to directive scoping
============================================================

1. httpd -h

Under "httpd -h" one gets a nice English description in which scope a
directive can occur. But we talk here only about <Directory> and <Location>,
although <Files> is treated the same (also with `cmd->override ==
ACCESS_CONF|OR_ALL'). So I think it's correct to also list <Files>, too.

2. Used scope variants

Currently we have 203 directives and they use the following scopes (the
numbers in parenthesis gives the number of directives using a particular
scope):

   RSRC_CONF (106)
   RSRC_CONF|ACCESS_CONF (5)
   RSRC_CONF|ACCESS_CONF|OR_ALL (1)            <--
   RSRC_CONF|ACCESS_CONF|OR_AUTHCFG (2)        <--
   ACCESS_CONF (5)
   OR_AUTHCFG (20)
   OR_LIMIT (3)
   OR_OPTIONS (4)
   OR_FILEINFO (21)
   OR_INDEXES (23)
   OR_ALL (13)

This is well spreaded and sounds reasonable. Except for
the two classes:

   RSRC_CONF|ACCESS_CONF|OR_ALL (1)
   RSRC_CONF|ACCESS_CONF|OR_AUTHCFG (2)

The first one is just a syntax overkill. It means only OR_ALL, because OR_ALL
includes (implicitly) already RSRC_CONF and ACCESS_CONF. So, when we fix
this to OR_ALL we get:

   RSRC_CONF (106)
   RSRC_CONF|ACCESS_CONF (5)
   RSRC_CONF|ACCESS_CONF|OR_AUTHCFG (2)        <--
   ACCESS_CONF (5)
   OR_AUTHCFG (20)
   OR_LIMIT (3)
   OR_OPTIONS (4)
   OR_FILEINFO (21)
   OR_INDEXES (23)
   OR_ALL (14)

The remaining RSRC_CONF|ACCESS_CONF|OR_AUTHCFG is used by two directives:
UseCanonicalName and ContentDigest. Two not too old directives which were
added mostly at the same time. They're are implemented the same way.
But the scope looks incorrect. Why?

First, it's again syntax overkill, ok. We can reduce it to
RSRC_CONF|OR_AUTHCFG. But when we compare it to all other used scopes, it
looks very inconsistent. No other of the 203 directives want to be applicable
in such a non-orthoginal scope: on the first hand inside the AuthConfig scope
(which means .htaccess under "AllowOverride AuthConfig" plus _INSIDE_ of
<Directory>/<Location>/<Files> sections in httpd.conf only) and on the other
hand also in RSRC_CONF (which means _OUTSIDE_ of
<Directory>/<Location>/<Files> sections in httpd.conf only). Sure, finally
it's everywhere in httpd.conf plus .htaccess under AuthConfig scope.  But it's
not intuitive: Directives which want to be applicable in such a total scope
use OR_OPTIONS, OR_FILEINFO or OR_INDEXES. And when we think about
UseCanonicalName and ContentDigest we find out that they belongs more to
Options, XBitHack and CheckSpelling than to any AuthXXXX directives.

So, I propose to change the scope of those two directives to OR_OPTIONS.  It
makes no big difference, of course. It still is useable everwhere inside
httpd.conf, but inside .htaccess now under Options instead of AuthConfig.  And
it both belongs to the more correct group of directives and makes our list of
used scopes more consistent.

With the above patch be get this consistent scope-list:

   RSRC_CONF (106)
   RSRC_CONF|ACCESS_CONF (5)
   ACCESS_CONF (5)
   OR_AUTHCFG (20)
   OR_LIMIT (3)
   OR_OPTIONS (6)
   OR_FILEINFO (21)
   OR_INDEXES (23)
   OR_ALL (14)

When we take into account that _theoretically_ there are a lot more variants
of these or'ed values are possible, this list is _VERY_ clean. Actually it's
the most clean variant I can think of (except for the fact that the whole
mechanism is a horrible mess ;-)...

      Cleanup the command line options: `-?' was documented to show the usage list · 504559df
      Ralf S. Engelschall authored 
      but does it with an error because `?' is not a valid command. OTOH a lot of
users expect `-h' to print such a usage list and instead are annoyed for ages
by our huge unreadable list of directives.  So we now changed the command line
options this way:

 1. `-L' => `-R'
    Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
    very similar to the popular linker option.

 2. `-h' => `-L'
    Intent: while -l gives the small list of modules, -L now gives the
    large list of directives implemented by these modules.  This is also
    consistent with -v (short version info) and -V (large version info).

 3. `-?' => `-h'
    Intent: it's now the expected option ;-)

The manual page was adjusted accordingly.
