Re: Make awk more friendly to multiline function declaration

The point is whether awk can be made more resilient to different types
of users' input or not.

The requirement of an extra backslash is unnecessary. Removing that
requirement can leave users with the freedom to format the code in
multiple lines. This is especially true when awk lacks the concept of
local variables. In that case, putting "local" variables in separate
lines will make the code more readable. This should be a rather common
thing to experience when you start writing awk functions.

Awk syntax should make it easier for users by not requiring an extra
backslash to be added when the comma is at the beginning of the line.
