Comment (by ddumont):

 I've found the same behavior with sshd lenses and a small sshd_config
 file. The bug looks related to the generation of the index between square
 brackets.

 When playing with augtool and sshd lense, I've found that:
 * print gives correct result
 * print /files/etc/ssh/sshd_config/Match/Condition is wrong (messed up
 indexes in Condition)
 * match /files/etc/ssh/sshd_config/Match/Condition is wrong

 In more details, 2 wrong outputs:
 {{{
 augtool> match /files/etc/ssh/sshd_config/Match/Condition
 /files/etc/ssh/sshd_config/Match[1]/Condition = (none)
 /files/etc/ssh/sshd_config/Match[2]/Condition[1] = (none)
 /files/etc/ssh/sshd_config/Match[2]/Condition[2] = (none)
 /files/etc/ssh/sshd_config/Match[3]/Condition[2] = (none)
 /files/etc/ssh/sshd_config/Match[3]/Condition[3] = (none)
 /files/etc/ssh/sshd_config/Match[3]/Condition[4] = (none)
 augtool> print /files/etc/ssh/sshd_config/Match/Condition

 /files/etc/ssh/sshd_config/Match[2]/Condition[1]

 /files/etc/ssh/sshd_config/Match[3]/Condition[4]

 }}}

 Whereas print result is correct:

 Unfortunately, this bug breaks the linkage between Config::Model and
 Augeas :-(


 Hope this helps
