[tex-k] Possible bug in TeX version 3.14159265

[Jonathan Kew]

This is not a bug. See module 28 (where a_close and friends are 
defined), which explicitly says that they "should not generate error 
messages if a file is being closed before it has been successfully opened".

So it's expected that a_close may be used in this way, and it's up to 
the implementor on any given system to ensure this is OK.
