Re: is this data corruption?

[Samuel Wales <samologist@gmail.com>]

as expected, there is only one copy of bigpart is a partition in all
of my rsnapshot files and all of my emacs backup files.

therefore, the diff in git and magit are incorrect.  it was not a
question of me removing a duplicate.

for future reference, is this mailing list correct for this question
or should i use the git help list which i discovered just now?
