If I'm editing an encrypted file then use the same Vim session to edit
a non-encrypted file, the saved undo information for the non-encrypted
file is garbled when it is read.
To reproduce, you need an existing, non-encrypted file that has undo
information saved, and an existing encrypted file (it doesn't matter
how 'cryptmethod' is set).
Start Vim:
vim -u NONE -U NONE -N -c 'set undofile' encrypted_file
Then do ":e otherfile" (where "otherfile" is the non-encrypted file
with previously saved undo information), and press 'u' a few times.
When this happens, all I have to do is ":qa!" and edit the
non-encrypted file again, and the undo information is properly read.
Unless I make the mistake of saving new changes to the non-encrypted
file--then the undo file becomes useless.
