Since we don't switch the window anymore, we can't simply refer to b:sy as we
used to do while Sy worked only synchronously.
Now we provide the buffer number to each job and the exit handler gets a pointer
to the b:sy of that buffer and passes it to all the subsequent functions.
References #209, #210.
Vim provides 2 arguments to the exit handler whereas Neovim always provides 3.
Change function signature to handle an optional third argument, even if it never
gets used.
Fixes#204.
For each new buffer sy#repo#detect() gets run. That function invokes callbacks
for all VCS from g:signify_vcs_list.
If no callback finds a valid repo, sy#set_signs() is never called and the VCS
type of the newly registered buffer keeps its initial value: "unknown".
The next time Sy gets run in that buffer, Sy will disable itself, so that all
subsequent times it gets run it will never even attempt to get a diff.
If a buffer was added to a repo that was initialized after Sy registered that
buffer, it will remain inactive.
In those cases, :SignifyEnable will purge the cache for the current buffer and
start all over.
This makes all Signify signs use a non-breaking space as text. This is
convenient if only the background colors of the signs are important.
References #188.
The <nomodeline> flag for :doautocmd was implemented in 7.3.438. Certain
LTS distros, e.g. Ubuntu 12.04, come with even older Vim versions,
though.
Silently ignore the flag in such cases.

When a user isn't logged in, "accurev diff" will return an exit code of
52. Since the only well defined values are 0 or 1, treat anything else
as unversioned.
"accurev diff" returns 0 for no diff, 1 for differences, and 2 for error
(like not being run from a workspace). Use 2 to indicate the file isn't
being versioned by AccuRev so Sy properly sets the vcs type to AccuRev
for unmodified files.
