check-code: make 'missing whitespace in assignment' more aggressive

New warnings:

 >     a.b=ab
 missing whitespace in assignment
(the pattern did not accept '.' on the left hand side)

 >     a=a
 missing whitespace in assignment
(the right hand side pattern never matched a single character)

 >     a=a + 7
 missing whitespace in assignment
(the pattern only matched one character after the identifier following =)
