In the commands below, "main" is $main, and "arch" is $arch_branch.
I'm starting out with the arch branch checked out.

[cfriesen@localhost linux]$ git describe main
dynamic_ftrace_excluded-auto-mark-225-g7c2dc32
[cfriesen@localhost linux]$ git describe arch
dynamic_ftrace_excluded-auto-mark-225-g7c2dc32
[cfriesen@localhost linux]$ git tag -m 'a test tag' my_tag ncgl
[cfriesen@localhost linux]$ git describe arch
my_tag
[cfriesen@localhost linux]$ git describe arch
my_tag

So far so good.  Now I make a change to the arch branch, and add
another tag to the main branch.

[cfriesen@localhost linux]$ echo a > asdf
[cfriesen@localhost linux]$ git add asdf
[cfriesen@localhost linux]$ git commit
Created commit 4c8dfa7: blah
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 asdf

[cfriesen@localhost linux]$ git describe main
my_tag
[cfriesen@localhost linux]$ git describe arch
my_tag-1-g4c8dfa7


Now we add another tag to the main branch:

[cfriesen@localhost linux]$ git tag -m 'a test tag' my_tag2 main
[cfriesen@localhost linux]$ git describe main
my_tag
[cfriesen@localhost linux]$ git describe arch
my_tag-1-g4c8dfa7

I assume that since there were no code changes on the main branch,
it doesn't think that there is any difference between the two tags.
