no changes to good configs, but some bug fixes might reveal some invalid
configs ... and, of course, from time to time might be regressions...

This was a bug fix, due to a report on bug tracker when someone was
having two route blocks with the name like ABC-XYZ and ABC-JKL,
practically overwriting the route blocks and resulting in unexpected
behaviour.

Given that minus is reserved character used for difference operations,
an ID is ended by encountering it and the name was kept up to the sign.

I haven't been involved directly in the fix, although being asked about
the backport and I agreed to be done if it is a fix -- iirc, the issue
was causing a crash and the fix was ensuring that the module is loaded
in the proper order.

This seems to be a regression of the cseq increment that was reported by
one of your colleagues and he reported to be fixed after several patches
pushed by myself. There is another related issue open on the tracker,
but I got into traveling and didn't have the time to investigate more.
It is in my short to-do list.

Cheers,
Daniel
