Another case that this patch fixes is

—samples=../fate-suite

The problem is the colon behind concat, which it considers to 
be a separator and hence changes it to a semicolon.
When the samples-path starts with a slash, it might behave 
differently again, no sure.

I'll add a note to the commit message, explaining which cases 
it fixes.
