[x] history -s n set size of history buffer
[ ] fg and bg
[x] ~~printenv~~ and ~~setenv~~
[x] properly piping commands
[x] richer redirection, e.g. python test.py 2>out

printenv does not have to be a shell builtin and setenv is not the right name.

setenv:

# set key to value
key=value
# clear the value associated with key
key=

variable name can't start with digit [1]

grammar:

= Ident = r"[[:alpha:][:alnum:]*]" When should the env variable be set? Should bsh get all the way to is_builtin, return true, and then do the work in run_builtin.
