bug#3122: Error saving commit messages for bazaar (bzr).

[Stefan Monnier]

> Emacs version 22.3

Can you try and reproduce this bug with the Emacs-23 pretest?

Also, as far as I can tell, the code in vc-bzr.el (in Emacs-22.3 as
well as in the upcoming Emacs-23) checks (file-readable-p dirstate)
before reading the file, so could you check:

  M-: (file-readable-p 
"c:/library/code/python/annotatex/releases/test/.bzr/checkout/dirstate") RET

to see if it indeed returns t rather than nil.  And then try

  M-: (insert-file-contents 
"c:/library/code/python/annotatex/releases/test/.bzr/checkout/dirstate") RET

to check that it indeed signals the error you're seeing.

If indeed, file-readable-p claims the file is readable, but
insert-file-contents signals a "permission denied", then the problem
seems to be in the C code (or even deeper such that there's no way for
Emacs to predict that insert-file-contents will signal an error).
