I think you are communicating fine, but not fully understanding darcs.

try this:
initial patch creates hello.c
#include <stdio.h>

int main(int argc, char *argv[])
{
  printf("Hello world!\n");
  return 0;
}

second patch:
replace ./hello.c [A-Za-z_0-9] world universe

third patch, for conceptual clarity, created in another repository that 
had seen the first patch, but not the second (adds function wide_world):
hunk ./hello.c 3
+void wide_world()
+{
+  printf("Hello wide world\n");
+}
+
hunk ./hello.c 11
+  wide_world();
}

If patch2 was a replace patch, then the result of running the combined 3 
patch version would be:
Hello universe!
Hello wide universe

but if patch2 was a non-replace patch, then the result would be:
Hello universe!
Hello wide world
