linecolour only works if you also specify textcolour

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create an msc file with linecolour specified for an arc
2. generate the png or svg

What is the expected output? What do you see instead?
expected = coloured arcs.
instead = non-coloured arcs.

It seems to only enable colouring on arcs if a textcolour is also 
specified. Here's a sample that illustrates this. I would expect both lines 
to be coloured, but only the first one is.

msc
{
a,b;
a->b [ label="hello" , textcolour="#ff0000", linecolour="#ff0000"];
b=>a [ label="hello" , linecolour="#ff0000"];
}

What version of the product are you using? On what operating system?
Mscgen version 0.16 on Windows XP

file:

Hi

This also affects mscgen from svn revision 88. I believe that main.c line 1342 
is (at
least partly) responsible: 

    /* Check for entity arc colouring if not set explicity on the arc */
    if(arcTextColour == NULL)
       {
        arcTextColour = MscGetEntAttrib(m, startCol, MSC_ATTR_ARC_TEXT_COLOUR);
        arcLineColour = MscGetEntAttrib(m, startCol, MSC_ATTR_ARC_LINE_COLOUR);
       }

I think that this should have been two separate ifs.
