This is very unfortunate, because makefiles have a nasty syntax. The 
colon is very special, when it occurs at the right spot, but just about 
anywhere else it's just another character in a string. I help myself 
like this: Since regexps can hardly match that, all the more since Emacs 
doesn't have Perl's excluding "(?! ...)" I do this regexp last and check 
that a colon I find was not highlighted otherwise before. E.g.:

var := a \
b:c

${var:a=b} : x
echo yes: it works

Of these five colons only the one before "x" is special. Without 
highlighting the multiline string assigned to var "b:c" looks like a 
rule, as does the last line. And prior to my rework, the colon in 
${var:a=b} was also recognized as a rule separator.
