364e9ccb9c wordexp(3): fix some bugs with signals and long outputs
* retry various system calls on EINTR
* retry the rest after a short read (common if there is more than about 1K
  of output)
* block SIGCHLD like system(3) does (note that this does not and cannot
  work fully in threaded programs, they will need to be careful with wait
  functions)

7937c23d49 Terminate execl()'s argument list with a null pointer instead of a
null pointer constant. (The latter may be an integer constant, which
is not correct here.)

fe634ca75f Fix a number of bugs noticed by more extensive testing:
o Call waitpid() if an error occurs after forking the child process
   to avoid leaving zombies around.
 o Handle the WRDE_DOOFS|WRDE_APPEND combination correctly
 o Do not confuse $( substitution with $(( shell arithmetic
     (noticed by wollman)
 o Handle backslash escaping properly
 o Allow $( and ${ to be quoted

faea1495bf Add an implementation of the POSIX wordexp() and wordfree() functions,
which perform shell-style word expansion on strings. This is still a
little rough around the edges.
