Merge branch 'js/fetch-jobs'

"git fetch --jobs=<n>" allowed <n> parallel jobs when fetching
submodules, but this did not apply to "git fetch --multiple" that
fetches from multiple remote repositories.  It now does.

* js/fetch-jobs:
  fetch: let --jobs=<n> parallelize --multiple, too

        linkgit:git-fetch[1] and linkgit:git-pull[1] commands.
        Defaults to true.
  
+ fetch.parallel::
+       Specifies the maximal number of fetch operations to be run in parallel
+       at a time (submodules, or remotes when the `--multiple` option of
+       linkgit:git-fetch[1] is in effect).
+ +
+ A value of 0 will give some reasonable default. If unset, it defaults to 1.
+ +
+ For submodules, this setting can be overridden using the `submodule.fetchJobs`
+ config setting.
++
 +fetch.writeCommitGraph::
 +      Set to true to write a commit-graph after every `git fetch` command
 +      that downloads a pack-file from a remote. Using the `--split` option,
 +      most executions will create a very small commit-graph file on top of
 +      the existing commit-graph file(s). Occasionally, these files will
 +      merge and the write may take longer. Having an updated commit-graph
 +      file helps performance of many Git commands, including `git merge-base`,
 +      `git push -f`, and `git log --graph`. Defaults to false, unless
 +      `feature.experimental` is true.
