Misleading wording in -compute_density

[Eskapp]

When using lasinfo with argument -cd, the wording about the unit used is misleading.
Indeed, it seems that when the horizontal unit is unknown, the density is said to be in points per square unit. (This line in the code: https://github.com/LAStools/LAStools/blob/master/src/lasinfo.cpp#L4078)

Square unit is actually a unit that is defined as 100 square feet (as defined here: https://en.wikipedia.org/wiki/Square_(unit)).

Could you confirm that the square unit displayed in lasinfo does not correspond to the official square unit definition? Also, maybe a rewording could be done to avoid confusion.

I did not know such an alternate definition for "square" existed. I simply use the english word "square" in its meaning to "square" things such as "square feet" or "square meter" or "square kilometer" or - if the unit is now known then "square unit" for whatever the unit may be. I assume that most of my users will not confuse this as the other meaning of the term "square" is rather fringe, meaning not common in the LiDAR and pointcloud world.
