[PATCH v2 0/1] branch: introduce --show-current display option

v2 reroll of a previously-discussed patch. Thanks to everyone for their comments. Based on feedback:

1. Command is now a verb: git branch --show-current.

2. Changed to gitster's suggested implementation: nothing is printed
 if HEAD does not point to a symbolic ref. A fatal
 error if HEAD is a symbolic ref but does not start with refs/heads/.

3. Added a test to show this works with worktrees

A process question to the list. The patch adds a new localizable string that gets output in case of repository corruption. I happen to speak a couple of the languages that have po files. Is it accepted practice to also include po edits in my patch in such a case, or should that be left to the regular l10n workflow?
