As per Matthieu's comments, I have updated the tests, but there is still one
thing that is not working: log -@{yesterday} or log -@{2.days.ago}
For the other kinds of suffixes, such as -^ or -~ or -~N, the suffix
information is first extracted and then, the function get_sha1_1 is called with
name="-^" and len=1 (which is the reason for the changed condition inside Patch
4 of this series).
For -@{yesterday} kind of queries, the functions dwim_log,
interpret_branch_name and interpret_nth_prior_checkout are called.
1. A nice way to solve this would be to extend the replacement of "-" with
"@{-1}" one step further. Using strbuf, instead of replacing the whole string
with "@{-1}" we would simply replace "-" with "@{-1}" expanding the string
appropriately. This will ensure that all the code is inside the function
get_sha1_1. The code to do this is in the cover section of the 4th patch in this
series.
2. we could go down the dwim_log codepath, and find another suitable place to
make the same "-" -> "@{-1}" replacement. In the time that I spent till now, it
seems that the suffix information (i.e. @{yesterday} or @{2.days.ago}) is
extracted _after_ the branch information has been extracted, so I suspect that
we will have to keep that part intact even in this solution. (I am not too
sure about this. If this is the preferred solution, then I will dig deeper and
find the right place as I did for the first part of this patch)
Matthieu: Thanks a lot for your comments on the tests! test_commit has made the
tests a lot cleaner!

Siddharth Kannan (4):
revision.c: do not update argv with unknown option
revision.c: swap if/else blocks
revision.c: args starting with "-" might be a revision
sha1_name.c: teach get_sha1_1 "-" shorthand for "@{-1}"
