Inserting a new comment breaks formatting of following comments

[mikhirev]

Hello!

I'm using Debian 9 with augeas 1.8.0. When I insert a new comment somewhere in the middle of any configuration file (checked with samba, systemd and ssh lens), e. g. smb.conf, formatting of all the comments below it breaks. #comment[last()] is formatted as the new comment should be, the new #comment[n] is formatted as old #comment[n] (now #comment[n+1]) etc.

% cp /etc/samba/smb.conf /tmp
% augtool --noload --noautoload
augtool> set /augeas/load/Samba/lens Samba.lns
augtool> set /augeas/load/Samba/incl /tmp/smb.conf
augtool> load
augtool> ins #comment after /files/tmp/smb.conf/target[2]/valid\ users
augtool> set /files/tmp/smb.conf/target[2]/#comment[preceding-sibling::*[1][self::valid\ users]] "New comment"
augtool> save
Saved 1 file(s)
augtool> quit

BTW this issue is not limited to comments, but also applies to all indexed nodes.
