There should be (and some protection against files that are modified
between when they are read in and when they are saved)

How about this API call:

        int aug_reset(augeas *aug, const char *path)
        
where PATH must match exactly one node in the tree, and that must
correspond to a file. Return 0 on success, -1 on failure.

For example, you could call reset on "/files/etc/hosts" to
reread /etc/hosts, but calling reset on any node underneath
"/files/etc/hosts" would be an error. Should resetting "/files/etc" or
even "/files" be allowed ?
