;; 2) Implement Stefan Monnier's advice:
|

;; vc-hg-registered and vc-hg-state
|
||
;; Both of those functions should be super extra careful to fail gracefully in
|
||
;; unexpected circumstances. The reason this is important is that any error
|
||
;; there will prevent the user from even looking at the file :-(
|
||
;; Ideally, just like in vc-arch and vc-cvs, checking that the file is under
|
||
;; mercurial's control and extracting the current revision should be done
|
||
;; without even using `hg' (this way even if you don't have `hg' installed,
|
||
;; Emacs is able to tell you this file is under mercurial's control).
