In my .emacs file I've got the following useful line:

  (define-key minibuffer-local-completion-map "~" 'insert-home-directory)

where `insert-home-directory' is a function which simply replaces the
current line by "~".  

This is nice, because when I'm editing system files and suddenly do C-x C-f
to load in a file from a subdirectory of my home directory, 
typing an initial ~ wipes out the current (system) directory from the 
minibuffer.  The system directory may be rather long, so deleting it is 
esthetically pleasing.

This trick works fine for find-file (i.e. C-x C-f) and friends.
Unfortunately it doesn't work for insert-file (i.e. C-x C-i), or
any function which calls read-file-name (which is coded in C).
Can anyone tell me why not?
