|
|
|
|
;; vc-hg-registered and vc-hg-state
|
|

|
2007-07-06 21:14:21 +00:00
|
|

|
;; unexpected circumstances. The reason this is important is that any error
|
2007-06-20 06:32:42 +00:00
|
|
|
|
;; 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).
