Log Message:
make(1): improve error message in case of unfinished modifiers
The previous error message "Unclosed substitution" was wrong for several
reasons.
It is not about "unclosed", but about "unfinished" since in the
:@var@...@ modifier the missing '@' does not really close anything.
The word "substitution" may have originated in a time where :S and
:from=to were the only modifiers, and these were indeed substitutions,
but several other modifiers aren't.
The :S and :C modifiers allow an arbitrary delimiter, therefore it is
helpful to enclose the delimiter in quotes, just in case someone chooses
')' or '{' or even ' ' as delimiter.
