[PATCH v2 1/2] bash completion: refactor common log, shortlog and gitk options

[Thomas Rast <trast@student.ethz.ch>]

Refactor options that are useful for more than one of them into a
variable used by the relevant completions.  This has the effect of
adding the following options to git-log:

  --branches --tags --remotes --first-parent --dense --sparse
  --simplify-merges --simplify-by-decoration --first-parent
  --no-merges

The following to git-shortlog:

  --branches --tags --remotes --first-parent

And the following to gitk:

  --branches --tags --remotes --first-parent --no-merges --max-count=
  --max-age= --since= --after= --min-age= --until= --before= --dense
  --sparse --full-history --simplify-merges --simplify-by-decoration
  --left-right
