[augeas-devel] "ins" statement in augtool can corrupt the edited file

[Marc Fournier]

Hello,

I noticed that when using the following statement in augtool, part of
the edited file gets lost (at least when using the inifile lens):

"ins item=value <WHERE> <PATH>"

I know this is not the way "ins" should be used, but it is tempting to
try to. Maybe augtool should catch this case and send an error to the
user instead ? Or perhaps "ins" could also work in this sort of
"2-in-1" mode ?

The following example illustrates the problem I came across:

marc at lonquimay:~/src/augeas/lenses$ augtool -I .
