bug in numapde-remove-extra-braces.awk
The script numapde-canonicalize-bibliography.sh removes a trailing brace. The sequence:
numapde-query-mathscinet.sh -m MR3984057 > MR3984057.bib
numapde-canonicalize-bibliography.sh MR3984057.bib
leads to the output

with a missing closing brace for the TITLE. The brace exists in the original file. Please also note, that the title has a line break, which might lead to the error.
