Good idea, at least at first and second glance.

A well-founded fear: I used --link for a while, with good effect (my main
tools, emacs and patch, both deal well with hard-links), but had to trash
my entire revlib after a single ill-considered shell-redirection.
Downloading everything again over a slow net link was not fun.

I think --link is not a good idea in general except for trees that you
won't modify (though temporary trees that you don't modify are in fact a
very useful and common thing), or are similarly only used in restricted
ways.

Perhaps tla could somehow assist this by providing a way to easily make
all files in a project tree read-only, e.g., `tla get --link --read-only'?
I guess it would have to add some meta-data indicator to tell mkpatch not
to do any permission bit comparisons against that tree.

Suburbia: where they tear out the trees and then name streets after them.
