Is the subject here taken from first message in the thread or
is the subject changing in every message ? If the name is changing
(which I presume, cannot test), the list of files will look a bit
confusing. This could follow the git patch naming where the number is at
the beginning of filename.

The naming could also follow git way, dashes (-) between words and
replacing multiple --:s with just one - (like gsub(/--+/, '-'))
-- but in this case there could something in the filename to distinguish
from git patches as these patches may be `git am` -incompatible.
