* remove unused variables
* fetch branch name instead of HEAD
fix#3782, which was introduced by f1bacc1d3f
* disable git depth option for old git versions
fixes#3782
git support for `--depth` did not fully work in old git versions (before 1.8.2)
fall back to full clones/fetches on those versions
* raise required git version to 1.9.1 for depth option
* use correct depth argument in switch_version
When `version` is not specified, it defaults to "HEAD". "HEAD" is not a
remote tag, and it's not listed in the output of get_branches(), so we'd
keep repo_updated at the default value (None) and then return early with
changed=True in --check mode, even when before == after.
Fixes#3024.

fall back to full clones/fetches on those versions
* fix git switch branches in combination with depth
* the old implementation is correct, but relies on git working correctly
(as only newer versions do)
* with some older git version (e.g. 1.8.3), git fetch remote branch does
not work, if the branch does not yet exist locally
* this patch works around that without explicitly checking the git version
* future refactoring is needed to reduce the number of fetches to a
minimum; but this patch makes the code "correct"
* add git version requirements to doc
* replace set-branches with git 1.7.1 compatible version
From the git status doc:
--porcelain
Give the output in an easy-to-parse format for scripts. This is similar to the short output, but will remain stable across Git versions and regardless of user configuration. See below for details.
User configuration can break the git module from working as expected.
* 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
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).
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.
