Git - print file creation dates

Scenario:

You have a directory of files in a git repository and you want to extract their original creation dates. Git does not track file creation date metadata, but you can get the first time the file was added in a commit.

This one-liner will print the dates and filenames sorted, in column format.

	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
