Map file: comments may interfere with EXPRESSIONs

[sweykam@…]

I found some interference between #comments behind the EXPRESSION: 

  EXPRESSION ([Riq50] <=1) didn't show while    EXPRESSION  '1' did 

Problem identified: 
Any #comment which contains brackets and parenthesis makes the expression fail 
(is apparently not understood as comment) unless the expression itself does not 
contain any brackets and parenthesis.
For example:
  EXPRESSION  ([Riq50] >1)    # ([Riq50] >1)    - fails
and 
 EXPRESSION  ([Riq50] >1)    # ('[Utm50km]' = 'VH4')    - fails
while 
  EXPRESSION  '1'  # ([Riq50] >1)    - is OK
and 
 EXPRESSION  ([Riq50] >1)    - is OK

In the first two cases there are parenthesis and brackets, both in the 
expression and in the comment. 
Funny thing.
