Hi guys, long time no see !

Indentation in the METAPOST mode has, IMO, two major flaws :

1. A bug. If the buffer starts with beginfig, the contents of the figure
is not properly indented (it stays on the first column).

2. When wrapping an expression on several lines, the indentation is the
same for each line, this is bad style : I'd prefer

beginfig(1)
  draw (0,0)--(1,2)--(10,3)--
    (0,1)--(10,3);
  draw (2,2);
endfig

I propose the following patch which considers that keywords like
beginfig does not need ending semicolon (it's /quite/ the case).

Tell me if it's worth installing it.
