Non-critical errors being sent to log when all.links files are read

[seasidesparrow]

Errors are being logged from reader.py, Line 226 (_get_bibcode) claiming that a bibcode of nonstandard length is being read in on line N, where N is one more than the number of lines in the all.links file. The logic of how reader is detecting EOF isn't clear to me, but it appears that the existing logic isn't trapping the EOF properly; it looks like it's reading a null line and then passing it as some kind of formatted string, ", ", which then misses both the check for None and the check for a 19-character bibcode.
