100 | ;; vc-hg-registered and vc-hg-state |
101 | ;; Both of those functions should be super extra careful to fail gracefully in | |
a07e665b | 102 | ;; unexpected circumstances. The reason this is important is that any error |
248c6645 DN |
103 | ;; there will prevent the user from even looking at the file :-( |
104 | ;; Ideally, just like in vc-arch and vc-cvs, checking that the file is under | |
105 | ;; mercurial's control and extracting the current revision should be done | |
106 | ;; without even using `hg' (this way even if you don't have `hg' installed, | |
107 | ;; Emacs is able to tell you this file is under mercurial's control). | |
