I don't understand this comment.  How is it "severely limiting"?

Granted, it won't properly parse
    export a=b c=d e=f foo bar
and I didn't account for extra whitespace.  The OP didn't specify any
such requirements though.

But it's not going to get tripped up by any line that doesn't match the
pattern.  It won't run off and execute any of the other commands in this
bash file.

I'm not personally offended by your comments, I'm curious to learn more.
