Hi Matt,

just wondering why you would want this? The point of sourcing a shell file is
to allow for the file to execute in the current (callers) shell environment.
For example, to allow all subsequent sub-shells to inherit from that parent -
useful for setting envrionment variables etc. 

However, I cannot see this being of any real use from inside emacs. No matter
what way you call it, emacs will spawn a sub process to execute the command.
Once it exits, everything is lost. However, I'll readily admit I may be missing
some application/reason and am just curious. 

To answer your question, there are no existing commands that I know of which
will do what you want. However, it wold only take about 5 lines of elisp to
create your own. 

Tim
