put includes hidden folders like .git

[lhoff94]

When i use ampy put to copy the content from my dev folder on my computer to the Micropython board it always copies the .git directory and there is no way to prohibit that.

Expected behaviour:
Put omits files and folders that are hidden. Maybe ad a flag to also include hidden files if needed.

Actual behaviour:
Put copies complete source folder including hidden directories and files to target.
