/stdhome

* fix add/ci command's recursion

if i go: stdhome ci ~/somedir, will it add the whole damn dir, or just the dir

itsself?  recursion needs to be requested, i think, by the -R switch

* add --all-files to `stdhome st` to show status of all files in repo?  or

   should we add `stdhome ls`? I'm favouring ls right now...

* symlink substitutes don't acept a symlink in the repo and a directory on the

   FS (as well as the other way around).  Should they?  I can't think of a use

   case for this...  Note: if this is changed, also update the StatusWalker

   (used by status and diff commands)

* add ~/bin/rebuild-tags!

* make the copy walker accept symlinks in place of files (as well as

   directories) if they are on the symlink accept list

* look at what need to be done before v0.1

* !!! TAG 0.1 !!!

* check directory permissions before updating them

* during copy-out (not copy-in), show what is being changed with lines like

   "<SP><SP><OP><SP><FILE>" where OP is A (add), D (delete), M (modified) and K

   (kind change)

* currently, verbose print lines for bzr stuff are in the commands -- should

   they be in the bzr module?

* make the copy walker accept symlinks that differ if they are on the symlink

   accept list (so that symlinks can be pointed elsewhere in ~/)

* add code that can determine a relative file from a full file and a basepoint

* when ignoring files in the walker, populate the list of file more

   inteligently.  ".bzr" (and ".bzrignore") need to come from the VCS backend.

   ".stdhome", ".stdhomerc" and/or ".stdhomeignore" need to be converted to full

   filenames and then their relative file names derived from the configured home

   directory

* KNOWN ISSUE: handle renames as renames (rather than delete + add) because a

   directory renamed in the repo could contain other stuff that isn't versioned

   in ~/ which is lost, at the moment

* KNOWN ISSUE: decide on whether to implement remote --keep flag (see plan:483);

   currently, on the remote end, stuff deleted in repo during an update deletes

   files in ~/
