Hi all.

I noticed that copy_segments in namespace detail::copy_segments (I am 
referring to the develop branch) does not output spikes of linear 
geometries. This particular free function is used in linear/areal set 
operations (in case you have not already spotted that). Is there a 
particular reasoning behind this behavior?

My motivation is the following: I am using copy_segments and 
action_selector for implementing linear/linear set operations; there I 
want to support spikes of linear geometries, which means that the 
current code cannot be used as is.

I have also extended the behavior of copy_segments and action_selector 
to allow for outputting spikes (by added a boolean template parameter). 
See the commits (in chronological order):

https://github.com/mkaravel/geometry/commit/65e111866945b8d7a3732f8b491d432143bd5a7c 

* 
https://github.com/mkaravel/geometry/commit/98e6dd3783ebb3b7758335da5ab195788b891bd7 

As of the second commit, the default behavior is backward compatible (so 
no breaks in existing code are expected).

All the best,

- m.
