dh-make-golang (or perhaps git-buildpackage) sometimes fails to find
upstream git tags, even though they exist:

$ dh-make-golang make -type l -git_revision v1.0.0 github.com/bradenhilton/mozillainstallhash

However, if we clone the git repository, we see that the tag exists:

$ git tag; git reset --hard v1.0.0
v1.0.0
HEAD is now at 1eb17be Update README

[As a separate wishlist, which should get its own bug: it would be
helpful for debugging purposes if dh-make-golang had a flag to keep it
from cleaning up after itself in the event of failure.]

It looks like the issue with v1.0.0 tag here is some sort of github
external origin issue.  This seems to be resolved with the  v1.0.1 tag.
 If you use a web browser to examine the older v1.0.0 tag, you see a github
warning of "This commit does not belong to any branch on this repository,
and may belong to a fork outside of the repository."  IOW, use v1.0.1 and
the previous error is gone.

Example make succeeds:
dh-make-golang make -type l -git_revision v1.0.1
github.com/bradenhilton/mozillainstallhash

Any chance we can move forward with the chezmoi package if this
mozilainstallhash dependency can now build successfully ?  I'm willing to
help test.
