Signed-off-by: Zebediah Figura z.figura12@gmail.com --- Fixes e.g. msacm.l3acm being enumerated as "msac".".l3a".
This behaviour matches that on Windows tested mainly by manually modifying the registry. If this is appropriate for a test I will add one.
v2: fix bad index breaking enumeration from system.ini
