env: Hide '.' variables in env print by default
When printing all variables with env print, don't print variables that begin with '.'. If env print is called with a '-a' switch, then include variables that begin with '.' (just like the ls command). Variables printed explicitly will be printed even without the -a. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
