floating point .8 and 5. in various combinations

The corresponding issue in LibreOffice is https://bugs.freedesktop.org/show_bug.cgi?id=48068

The error has been discovered by test case "path-data-18-f.svg" from the W3C-SVG test suite. 

Read section "8.3.9 The grammar for path data". The BNF has
floating-point-constant:
    fractional-constant exponent?
    | digit-sequence exponent
fractional-constant:
    digit-sequence? "." digit-sequence
    | digit-sequence "."

That means, that in a fractional-constant
(A) a leading zero can be omitted if a digit-sequence follows the dot.
(B) a trailing zero can be omitted if a digit-sequence is before the dot.

The attached example should show a black line same as the green line but only shifted down a little bit.
 
In AOO the case A fails. The affects the third, forth, fifth and sixth bar in the example.

In Seamonkey the case B fails (first and second bar), Batik shows all cases correctly.
