Subject: 28.1.50; Disabling csv-align-mode leaves the buffer marked modified
Date: Fri, 24 Jun 2022 16:13:47 +0200

When disabling `csv-align-mode` (I enable it in `csv-mode-hook`, but sometimes I
need to disable and reenable it to fix the alignment), the buffer is marked as
modified. This is a bit unnerving, because the contents of the buffer isn't
really changed. (At first I thought I had fat-fingered my way into data
corruption, but git tells me it isn't that bad.)

Thanks,

Joost

Yup.  I've now pushed a fix to GNU ELPA.
