[REVIEW 3-5] fdo#48068 fix parsing of path d-attribute

[Christina Roßmanith]

Hi,

in a svg path "H 40.5.6" should be parsed in the same way as "H 40.5 .6"

commit bef8e358b6940fd4a976cb346dfd829643e581b8 makes the double parser 
stop if a second separator '.' is seen. Furthermore the test wether we 
are on a number returns 'true' for a '.' that parsing starts even 
without a digit preceding '.'.

Now the w3c test paths-data-18f.svg nearly passes - there is no red 
anymore - but there is no gold either  :-(
