In parse_name_and_email() function, there is this line:
*name = (nstart < nend ? nstart : NULL);
When the function is given a buffer "A <a...@example.org> <old@x.z>",
nstart scans from the beginning of the buffer, skipping whitespaces
(there isn't any, so nstart points at the buffer), while nend starts
from one byte before the first '<' and skips whitespaces backwards
and stops at the first non-whitespace (i.e. it hits "A" at the
beginning of the buffer). nstart == nend in this case for a
single-letter name, and an off-by-one error makes it fail to pick up
the name, which makes the entry equivalent to
<a...@example.org> <old@x.z>
without the name.
