Re: pathmap (again)

[Fernando Nasser <fnasser at cygnus dot com>]

Well, I like it this way.  It does not hurt the CLI language at all
so if you are looking for an "approval in principle" or something like that
consider it given.  I will not pest you with requests to change the command
interface anymore :-)

I can only answer for the CLI aspects though.  But I understood that people 
liked the idea of having this around, so if I did not misunderstood I believe
everybody is sort of waiting for the patch already.

The "insert" operation is interesting.  I think J.T. gave a good example of
a situation where it can be useful.  But I guess it is a simple thing to add
at any time, so we may test the concept by initially not providing it and
seeing if someone asks for it (out of a personal need) or even send a patch.

IMO you should go ahead with this and submit a patch.
