Adding D Editor Support

[John A. De Goes]

Turns out the ambiguous argument types is really the only true multiline (i.e. the one error that cannot be understood just by looking at what follows the colon on the first line).

-------------------

dsymbol.c:    error("Dsymbol '%s' has no size\n", toChars());
dsymbol.c:    //printf("Dsymbol::error()\n");
func.c:     error(loc, "called with argument types:\n\t(%s)\nmatches both:\n\t%s%s\nand:\n\t%s%s",
lexer.c:                    error("undefined escape hex sequence \\%c\n",c);
lexer.c:                    error("undefined escape sequence \\%c\n",c);
mars.c:     {   error("use -profile instead of -gt\n");
mars.c:     {   error("unrecognized file extension %s\n", ext);
root.c: error("Error reading file '%s'\n",name->toChars());
root.c: error("Error writing file '%s'\n",name->toChars());
root.c: error("Error appending to file '%s'\n",name->toChars());
template.c:     error("forward reference to template declaration %s\n", tempdecl->toChars());
toobj.c:                    error("%s %s is hidden in %s\n", fd->toParent()->toChars(), fd->toChars(), toChars());
