Re: Source code formatting: line length limit?

[Richard Stallman]

    To illustrate my problem:  I have just reformatted source code from
    something like 120 columns to something below 80.

Sometimes, in such cases, the best solution is to move some of the
deeply nested code into subroutines.  That reduces the nesting,
and enables you to keep the code within 80 columns easily without
requiring lots of line breaks.
