The problem with such look-ahead with a regexp on the line is that it
will miss expansion of @value or user-defined macros.  For example if we
have something along

 @macro mymacro
 @end macro

 @indent @mymacro{}

The four spaces in the macro before aaa will be in the paragraph, though
it should be outside (I believe).  In particular, this could potentially
mess up Plaintext indenting.
