support for editing krb.conf file

[ssbarnea]

krb.conf file is mostly an ini file but it still have something that makes in incompatible with crudini:

[realms]
EXAMPLE.COM = {
  kdc = kerberos.bos.example.com
  kdc = kerberos.corp.example.com
  default_domain = EXAMPLE.COM
}

Is it possible to edit this file with crudini? If not is there a workaround?

This would overlap with supporting lists. I.E. EXAMPLE.COM is a multiline item, and we might support editing items in the list. Anyway currently deleting the curly brackets gets you a "valid" ini file.
So you could preprocess like:

sed 's/= {/=/; s/^}/ignorelb_=_/'

And postprocess like:

sed 's/=$/= {/; s/^ignorelb_=_/}/'

Note kerberos config files can also be indented, which can be handled with the --ini-options=ignoreindent option
