  - tdf#123803 Add relelase info in Calc functions
    
    Patch is for REGEX function available since release 6.2
    
    To add release information to other functions look
    at the diff in func_regex.xhp and adjust the release. It
    should be straightforward:
    
    <embed href="text/scalc/00/avail_release.xhp#M.N"/>
    
    where M is version and N is release.
    
    Patch tweaked to minimize translation effort (only one string)
