This is only enforced for dynamically created signs, namely
g:signify_sign_delete and g:signify_sign_changedelete, if
g:signify_sign_show_count is on.

Having default values for options that depend on another option's value is a bad
practice. Be more explicit:
g:signify_sign_show_text is ON by default
g:signify_sign_show_count is ON by default
So, people who want just background colors and no text at all in their signs
have to set both:
let g:signify_sign_show_text = 0
let g:signify_sign_show_count = 0
Before this change, only the first line was needed.
This also fixes a bug that happened with:
let g:signify_sign_show_text = 0
let g:signify_sign_show_count = 1
Removed lines wouldn't show a count whereas changed + removed lines would.
When you have nested repos of different VCS and you edit a file from the inner
repo, more than one VCS can return a valid diff. Only one VCS should return a
non-empty diff, though.
Once a non-empty diff is found, all other VCS get disabled to reduce overhead.
References #235.
Before this change, it was possible that a buffer was disabled, when Sy was run
more than once at startup, e.g. because of `BufEnter` and `FocusGained`.
The first call would start the detection and the second call would disable the
buffer, because the first call hadn't changed the VCS type from "unknown" yet.
To avoid issues for Vim versions between 7.4.1966 and 7.4.2071, we now use
type() to distinguish between the type of variable `job_id` being either Number
or Job.
Before Vim 8.0.50, an exited job was only detected with a potentially huge
delay.
Thus, for versions smaller than 8.0.50, we add a close_cb callback that runs
job_status() which in return runs the exit_cb callback immeditely if the job was
found to be dead.

References: #216.
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.
