[PATCH v5 00/11] forking and threading

v5 addresses the issues with creating the child's environment.  Instead of
doing vanilla C string manipulation, I used a struct string_list and struct
strbuf.  The code should be much easier to read and understand now.  I also
needed to add a function to remove a string_list_item from a string_list to the
string_list API.

Brandon Williams (10):
  t5550: use write_script to generate post-update hook
  t0061: run_command executes scripts without a #! line
  run-command: prepare command before forking
  run-command: use the async-signal-safe execv instead of execvp
  string-list: add string_list_remove function
  run-command: prepare child environment before forking
  run-command: don't die in child when duping /dev/null
  run-command: eliminate calls to error handling functions in child
  run-command: handle dup2 and close errors in child
  run-command: add note about forking and threading

Eric Wong (1):
  run-command: block signals between fork and execve
