Additional patch for "Can't execute ..."

The patch I sent a couple of hours ago was not enough.  In fact
delimcpy() was used wrongly when splitting PATH on dosish systems: '\\'
is not quoting ';' in PATH.

Fortunately, delimcpy() is used in very few places in the source, and
never with ';' as delimiter - outside of PATH context.  So we just fix
delimcpy() when the delimiter is ';'.

Enjoy,
