Documentation: mention 'git stash pop --index' option explicitly

'git stash pop' supports the '--index' option since its initial
implementation (bd56ff5, git-stash: add new 'pop' subcommand,
2008-02-22), but its documentation does not mention it explicitly.
Moreover, both the usage shown by 'git stash -h' and the synopsis
section in the man page imply that 'git stash pop' does not have an
'--index' option.

First, this patch corrects the usage and the synopsis section.

Second, the patch moves the description of the '--index' option to the
'git stash pop' section in the documentation, and refers to it from
the 'git stash apply' section.  This way it follows the intentions of
commit d183663 (Documentation: teach stash/pop workflow instead of
stash/apply, 2009-05-28), as all 'git stash pop'-related documentation
will be in one place without references to 'git stash apply'.

 If the `--index` option is used, then tries to reinstate not only the working
 tree's changes, but also the index's ones. However, this can fail, when you
 have conflicts (which are stored in the index, where you therefore can no
 longer apply the changes as they were originally).
