[REVIEW 3-5] fdo#48070 fix parsing of arc paths

[Christina Roßmanith]

Hi,

I've changed lcl_importNumberAndSpaces to lcl_importFlagAndSpaces 
because it is only used to import flags (single digit). Values != 0 or 
=! 1 return false as does a '-'. Now missing white space between flags 
isn't a problem any longer.
