bug#7883: [PATCH] comint history expansion fails to process :N or $ modifier

This has been driving me nuts since I started using 23 and I only just now
bothered to find and fix it. This worked correctly in 22 and was broken,
apparently just by a careless change.
In a comint/shell buffer, type:
echo foo bar RET
and then type:
echo !$ TAB
and you get the expansion:
echo echo foo bar
i.e., the whole line as if !$ had been !!.
The expansion you should get is just:
The following trivial patch fixes the bug, restoring the behavior of v22
with similar code to what it had originally. I tested the fix in 23.2.1,
but the relevant comint.el code in the trunk has not changed since then.

* comint.el (comint-replace-by-expanded-history-before-point):
Fix expansion of !$ and !!:N syntax to pick the indicated word.
