Hi,

Now the repo is becoming large, the short prefix using 6 character can
be refer to 2 Git objects. For instance,

Toggle snippet (8 lines)
$ git show 7022eb6
error: short object ID 7022eb6 is ambiguous
hint: The candidates are:
hint: 7022eb6ea0 commit 2021-12-07 - gnu: Add notcurses.
hint: 7022eb6c9a blob
[..]

The issue is the error report by “guix time-machine” (or guix pull), for
instance,

Toggle snippet (4 lines)
$ guix time-machine --commit=7022eb6 -- help
guix time-machine: error: Git error: ambiguous SHA1 prefix - found multiple pack entries

It could be nice that, when short prefix is ambiguous:

1) try the commit object candidate if only one
2) show a hint for the possible candidates


Cheers,
simon
