[pacman-dev] [PATCH 2/5] query_fileowner: avoid buffer overflow

[Andrew Gregory]

Copying a string into a buffer that  has just been determined to not be
able to hold it is obviously incorrect.  The actual error handling
appears to have been unintentionally removed in
47762ab687959e48acc2de8592fcf3ba3cfa502b.
