"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.
This merge removes g:signify_diffoptions and replaces it by the much more
general g:signify_vcs_commands. Users can customize the entire command to be
run now.
This reverts commit 5cdf72acd17d3559e4b5a207dea2993ddd77f50d.
`shellescape()`, which is what `sy#util#escape()` is a front-end to, is
only supposed to escape a single element of an argv list. In this case,
it's being used to escape multiple -- `p4 info 2>&1 >`. None of that
should be escaped anyway, because they need to be interpreted by the
shell.
“p4 monitor info” isn't always available and can impose a heavy runtime
cost when it is if the server isn't responsive.
Closesmhinz/vim-signify#153

sy#stop() is called by the BufDelete autocmd so b: variables may not
correspond to the buffer actually being deleted. Instead, we must use
<abuf> to determine which buffer is being deleted and pass that into
sy#stop().
There are some ripple effects, causing sy#sign#remove_all_signs to also
gain a buffer number argument.
