Unrelated to your cleanups, but also a problem: This use of sscanf is
non-portable, and very likely to crash on non-glibc.  %a in C99 means to
scan a floating point number (similar to %f), which is _very different_
from glibc's older meaning of malloc'ing into the destination.  %m is
the preferred spelling for the intent of the code here.
