Follow-up Comment #1, bug #54630 (project make):
Another example is the advice not to omit parens in references to
single-character variables: "you could reference the variable x with ‘$x’.
However, this practice is strongly discouraged, except in the case of the
automatic variables..." I've found that in the bodies of user-defined
functions, particularly those already laden with parentheses, '$1' is
significantly more readable than '$(1)'. Suggested tweak: "the usual style is
to include the parentheses except in the case of automatic variables..."
Unless there's some reason other than style preference, in which case that
reason should be spelled out.
