Hi, Bram,
The attached one-line patch alters the behaviour of retrieving the 'key'
option.
Rather than always returning "*****" it returns the empty string if 'key' is
empty. While still protecting any key that is used, this is useful to be able
to
determine whether or not a file is encrypted, so you can, for example, disable
swap files with an autocommand depending on whether a file is encrypted or not.
It
shouldn't cause any compatibility issues, as no programmer should have relied
on
'key' always being "*****"; they could just hard code "*****" themselves!
Would you be able to include this?
Cheers,
Ben.
