Fix extended short SHA1 name completion

Browse Source 
get_sha1() would not do sha1 completion of short SHA1's when they were
part of a more complex expression.  So doing

	git-rev-parse 727132834e6be48a93c1bd6458a29d474ce7d5d5^

would work, and return 87c6aeb4ef. But using
the shorthand version

	git-rev-list 72713^

wouldn't work.
