**                     tag or branch creation.  If the value is "pullonly"
**                     then only pull operations occur automatically.
**                     Default: on
**
**    binary-glob      The VALUE is a comma or newline-separated list of
**     (versionable)   GLOB patterns that should be treated as binary files
**                     for merging purposes.  Example:   *.xml
**
**    case-sensitive   If TRUE, the files whose names differ only in case
**                     care considered distinct.  If FALSE files whose names
**                     differ only in case are the same file.  Defaults to
**                     TRUE for unix and FALSE for windows and mac.
**
**    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 CR+NL line endings.
