I too find that "@ is a shortcut for HEAD" looks ugly both at the UI
level and at the implementation level [*1*], but as long as we have
it, it is good to try to be consistent and allow "@" everywhere
where one would write "HEAD" in places where it is syntacitically
infeasible---at least we would be consistently ugly that way ;-).
The title of the change may want to be clarified to help readers of
"git shortlog". It's not like it is only changing "@" and no other
variants valid refspec, but it forces readers to make sure that the
author did not forget to deal with ":@", "src:@", "@:dst", etc.
"make @ a synonym to HEAD in refspec" or something along the line,
perhaps.
[Footnote]
*1* I shouldn't complain too much, as my own invention to silently
turn "-" given from the command line into "@{-1}" is ugly at the
code level the same way, even though it may be better at the UI
level.
