[vdr] DVB-T Channels – ERROR: invalid value for parameter 'S'

I recently updated from 1.7.22 to the latest VDR developer snapshot 1.7.27

My DVB-S/DVB-S2 tuners all continued to work fine, but none of my
DVB-T channels were accesible anymore.

Checking the logs I noticed numerous "ERROR: invalid value for
parameter 'S'" entries, whenever attempting to tune to a DVB-T
channel. I presumed this was related to the changes introduced into
1.7.23 for not writing values to channels.conf that weren't valid for
the given delivery system, but I couldn't find anything in the
Changelog that indicated a channels.conf change was needed.

I guessed the simplest way to fix this was to use VDR's channel editor
to 'edit' and save my DVB-T channels, without modifying anything, and
seeing what change was introduced in channels.conf

- ITV1:642000000:B8C23D12G32M64:T:0:520=2:521=eng at 3,522=eng at 3:0;523=eng:0:8271:9018:8207:0
+ ITV1:642000000:B8C23D12G32M64S0T8Y0:T:0:520=2:521=eng at 3,522=eng at 3:0;523=eng:0:8271:9018:8207:0

It is trivial for me to reproduce this for all my channels. However, I
presume this means that scan / w_scan etc. all need to be updated to
generate the new channels.conf format for VDR 1.7.23 and newer?
