**    binary-glob      The VALUE is a comma or newline-separated list of

**
**    clearsign        When enabled, fossil will attempt to sign all commits
**                     with gpg.  When disabled (the default), commits will
**                     be unsigned.  Default: off
**
**    crnl-glob        A comma or newline-separated list of GLOB patterns for
**     (versionable)   text files in which it is ok to have NL or CR+NL line
**                     endings. Set to "*" to disable NL/CR+NL checking.
**
**    default-perms    Permissions given automatically to new users.  For more
**                     information on permissions see Users page in Server
**                     Administration of the HTTP UI. Default: u.
**
**    diff-binary      If TRUE (the default), permit files that may be binary
**                     or that match the "binary-glob" setting to be used with

** Return a pointer to the translated text.
** Call fossil_filename_free() to deallocate any memory used to store the
** returned pointer when done.
**
** This function must not convert '\' to '/' on windows/cygwin, as it is
** used in places where we are not sure it's really filenames we are handling,
** e.g. fossil_getenv() or handling the argv arguments from main().
**
** On Windows, translate some characters in the in the range
** U+F001 - U+F07F (private use area) to ASCII. Cygwin sometimes
** generates such filenames. See:

<title>Change Log</title>

<h2>Changes For Version 1.26 (as yet unreleased)</h2>
  *  Win32: Fossil now understands Cygwin paths containing one or more of
     the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in
     win32. This means that the win32 fossil.exe is better usable in a Cygwin
     environment. See
     [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars].
  *  Cygwin: Fossil now understands win32 absolute paths starting with a drive letter
     everywhere. The default value of the "case-sensitive" setting is now FALSE.
  *  Enhancements to /timeline.rss, adding more flags for filtering
     results, including the ability to subscribe to changes made
     to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82].
  *  JSON API: added the 'status' command to report local checkout status.


<h2>Changes For Version 1.25 (2013-02-16)</h2>
  *  Enhancements to ticket processing. There are now two tables: TICKET and
     TICKETCHNG. There is one row in TICKETCHNG for each ticket artifact.
     Fields from ticket artifacts go into either or both of TICKET and
     TICKETCHNG, whichever contain matching column names. Default ticket 
     edit and viewing scripts are updated to use TICKETCHNG. The TH1
