Null characters in branch name?

[Rick Rankin]

Well, turns out I figured out how to fix the problem. One way, at least, is
to use the "convert" extension using the branchmap feature. From the "od"
output of the "hg branches" command, it's apparent that the bad branch name
has exactly 8 null characters. I created a branchmap file containing a from
name with 8 nulls and a to name of "null-branch":

^@^@^@^@^@^@^@^@ null-branch

where ^@ represents a null character. Then, I used the command

hg convert --branchmap branchmap repo-with-null-branch-name new-repo

After looking at the new-repo, all seems fine.

Maybe this will help someone else someday.
