Probably want parentheses around c.
Right, I'll fix it before pushing.

Thanks, pushed now.
But the pre-existingcode seems odd - this is used to parse the INI-like syntax files for auth: https://libvirt.org/auth.html
It does not really make sense to allow form feed or del in the group entry name. I guess the only remotely reasonable character we'd block by switching to g_ascii_isprint here is '\t'
I was considering to "fix" the code as well but when looking into what GLib offers we can replace this whole file with GKeyFile [1].
Yes, if GKeyFile is compatible with what we're currently parsing, we should definitely just replace it Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
