reasons:
* This option is called "bad practice" in gerber files format specifications and is even forbidden in gerber drill files.
* Generates problems with some board makers because these holes are not identified in a single NC file.
* No one was able to explain us how to identified them in a single NC file.
* Recent change in drill file generation is not compatible with merged holes (minor reason)
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
Mainly to plot drill maps, but can be used to plot boards, for documentation.
The print svg still exists, but the plot SVG has more options (mirroring, holes in pads),
however print svg allows color print, and full board printing, and plot does not.
