This command (.uno:Repeat) works only in Writer and Calc. It is always
inactive (greyed out) in Basic IDE.

But there are way too many codes calling that one.  Maybe someday...

When leaving the mouse over a header or footer area for 2 seconds, the
separator is shown. This feature enables adding headers and footers
easily without knowing anything about page styles.

The separators are hidden back after 2 seconds outside the header or
footer area.

 - BrowseBox: Check Handle column-related invariants when adding a
   column:
   # only one handle column
   # it is the first

 - BrowseBox: Check column id-related invariants when adding a column:
   # Id is not the special "handle column" value
   # Id is not the special "invalid ID" value
   # unicity of the ID among columns

 - GetColumnId: return BROWSER_INVALIDID, not 0 (== id of handle
   column) for an invalid column; adapt code calling GetColumnId to
   this change.

 - Use the correct const or #define'd symbol instead of magic
   constants; introduce such a symbol if needed

 - General other miscellaneous cleanups:
   # Translation of comments
   # typo/spelling in comments, error messages and the like
   # parenthesise #define'd value
   # use SAL_MAX_UINT16 instead of USHRT_MAX where a sal_uInt16 is
     expected
   # BrowseBox::SetColumnTitle: nItemId is checked to be non-zero, so
     don't test if for zeroness again.

make it clearer that DbGridControl_Base::RemoveColumn
is meant to be called unconditionally
