function! ingo#selection#patternmatch#AdaptEmptySelection()
"******************************************************************************
"* PURPOSE:
"   With :set selection=exclusive, one can create an empty selection with |v| or
"   |CTRL-V|. The |/\%V| atom does not match anywhere then. However, (built-in)
"   commands like gU do work on one selected character. For consistency, custom
"   mappings should, too. Invoke this function at the beginning of your mapping
"   to adapt the selection in this special case. You can then use a pattern with
"   |/\%V| without worrying.
"* ASSUMPTIONS / PRECONDITIONS:
"   A visual selection has previously been established.
"* EFFECTS / POSTCONDITIONS:
"   Changes the visual selection.
"   Clobbers v:count when active.
"* INPUTS:
"   None.
"* RETURN VALUES:
"   None.
