* make git updates respect depth
until now `fetch` gets all tags and heads at full depth, this change
* uses `depth` argument for `fetch`
* only get the specified `version` in `fetch`
* fixes#14954
* treat combination of refspec and depth correctly
* be more conservative for non-depth fetch
The command `hg up -C` by default moves to the latest revision on the
current branch. The `discard` function was trying to update to a
different branch, in case it was provided, by passing a `-r REVISION`
argument. Not only is this not the intended effect of the `discard`
function, but this also could update to a different branch that hasn't
been pulled yet, which is how we were experiencing trouble.
Instead, we unconditionally do `hg up -C -r .` to "update" to the
current revision (i.e. to "."), while `-C/--clean`ing the current
directory. This is similar to `hg revert --all`, except that it also
undoes the merge state of the working directory, in case there was
any.
Detached head detection seems to have broken somewhere a long the way
because git decided to change how that situation looks when doing a 'git
branch -a' which is performed by get_branches().
This is how git 1.7.1 displays this situation (which works):
shell> git branch -a
* (no branch)
master
This is the output from git 1.8.3.1 (which does not work):
shell> git branch -a
* (detached from e132711)
master
It looks like this same wording is used in the most recent version of
git (2.6.1 as of writing this).

Fix: Ignoring svn:externals on local Modification Check.
Add: Added Argument switch to alow skipping the svn switch call.
When a SVN repository has some svn:externals properties, files will be
reported with the X attribute, and lines will be added at the end to
list externals statuses with a text looking like
"Performing status on external item at ....".
Such lines were counted as a local modification by the regex, and the
module returned a change, even though they were none.
To have a clean (and parsable) "svn status" output, it is recommended
to use the --quiet option. The externals will only appear if they have
been modified. With this option on, it seems even safer to consider
there are local modifications when "svn status" outputs anything.
This argument may be used to fetch additional refs beyond the default
refs/heads/* and refs/tags/*. Checking out GitHub pull requests or Gerrit
patch sets are two examples where this is useful.
Without this, specifying version=<sha1> with a SHA1 unreachable from any
tag or branch can't work.
De-duplicate repetitive code checking the exit code.
Include the stdout/stderr of the failed process in all cases.
Remove the returned values because no caller uses them.
Combine git commands where possible. There is no need to fetch branches
and tags as two separate operations.
