The variables B S and D control this but are cleaned from the environment when a shell is started.  Add a new variable to allow additional variables to be kept for a developer shell and set it to "B S D" by default.  The implementation allows variables for developer convenience and verification while not changing shells used for compile tasks.

Also, the summary of the commit message should start "devshell: " and
you should fold in the whitespace fix patch.
