[05/49] wined3d: Only add line numbers for new lines in shader_addline()

[H. Verbeet]

shader_addline currently always prepends line numbers when printing
shader output. This is a bit inconvenient, since it mean we must
always append a full line at once if we want to have readable traces.
This patch makes shader_addline only print the line numbers when the
last character in the buffer was \n. A more through way to check for
new lines would of course be to scan the entire line we add, but at
this point that's probably not worth it.

Changelog:
  - Only add line numbers for new lines in shader_addline()
