bug#1809: 23.0.60; epa-encrypt-file corrupts files

[Juri Linkov]

Test case:

1. Create a file `test' with the following 3 lines:

Test.
Test2.
Test3.

2. Save it.

3. Call `epa-encrypt-file' to encrypt it with no key
using symmetric encryption giving the password "test".

4. Visit the file `test.gpg' using the password "test".

5. The decoded buffer has the corrupted content:

^@est.
Test2.
Test3.

where ^@ is a NULL control character.
