Merge branch 'jk/rerere-xsnprintf'

Some calls to strcpy(3) triggers a false warning from static
analysers that are less intelligent than humans, and reducing the
number of these false hits helps us notice real issues.  A few
calls to strcpy(3) in "git rerere" that are already safe has been
rewritten to avoid false wanings.

* jk/rerere-xsnprintf:
rerere: replace strcpy with xsnprintf
