Fix extended short SHA1 name completion
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 87c6aeb4efdd4355918d127a91bd0adc5a02f8ff. But using
the shorthand version
git-rev-list 72713^
wouldn't work.
