git-prompt: make upstream state indicator location consistent

Browse source 
Make upstream state indicator location more consistent with similar
state indicators (e.g. sparse). Group the short upstream state indicator
(`=`, `<`, `>`, or `<>`) with other short state indicators immediately
after the branch name. Previously short and long upstream state
indicators appeared after all other state indicators.

Use a separator (`SP` or `GIT_PS1_STATESEPARATOR`) between branch name
and short upstream state indicator. Previously the short upstream state
indicator would sometimes appear directly adjacent to the branch name
instead of being separated.

For comparison, `__git_ps1` examples without upstream state indicator:
(main)
(main %)
(main *%)
(main|SPARSE)
(main %|SPARSE)
(main *%|SPARSE)
(main|SPARSE|REBASE 1/2)
(main %|SPARSE|REBASE 1/2)

Note that if there are short state indicators, they appear together
after the branch name and separated from it by `SP` or
`GIT_PS1_STATESEPARATOR`.

Before/after examples with short upstream state indicator:
| Before           | After            |
| ---------------- | ---------------- |
| (main=)          | (main =)         |
| (main|SPARSE=)   | (main =|SPARSE)  |
| (main %|SPARSE=) | (main %=|SPARSE) |
