Recommend using '**' to encrypt entire directories

[yuvipanda]

gitattributes now supports '' to mean 'entire subtree'. Using '*' instead of '' is an easy mistake to make with pretty bad consequences. Hopefully this added emphasis will make it less likely users make the mistake.

I would suggest taking it a step further:

**/.gitattributes !filter !diff
**/secret_* filter=git-crypt diff=git-crypt

The first line ensures that no .gitattributes file gets encrypted, regardless of which folder or subfolder it's in The second line is a simple way of making sure that any file with a name starting with "secret_" will get encrypted, regardless of which folder or subfolder it's in
