[PATCH v4 0/2] for-each-repo: new command for multi-repo operations

[Lars Hjemli <hjemli@gmail.com>]

Changes since v3:
* option -x used to execute non-git commands
* option -z used to NUL-terminate paths
* write_name_quoted() used to print repo paths
* repos are handled in sorted order (as defined by strcmp(3)) to get
  predictable output from the command
* unsetenv() reintroduced to avoid problems from GIT_DIR/WORK_TREE
* more tests

Lars Hjemli (2):
  for-each-repo: new command used for multi-repo operations
  git: rewrite `git -a` to become a git-for-each-repo command
