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.

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.
Closes https://github.com/mhinz/vim-signify/issues/185
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.
Previously, when using *nix csh-like (or probably ksh-like) shells, perforce
detection would fail with E484. This was due to hard-coded bash-like
redirection.
This change obeys the vim `shellredir` option when detecting perforce.
Use split() instead of substitute(), since the latter simply parses strings
and doesn't understand the notion of path separators. Backslashes would be
interpreted as beginning escape sequences.
Using split() works around this problem.
Closes#163.
