Point taken about the wrapping. I have changed the option in my email  client.

I have been surruptitiously working on a program, called pedant, which checks for compliance with the coding standard.

I was under the impression that 80 character lines were the limit, so I coded the test into pedant. But when I went looking for scriptural authority in the FSF or GCC coding standards, I couldn't find
anything that says there is a line size limit.

There should be such a limit IMHO. Perhaps it should be added to the GCC coding conventions document.

By the way there are over 1600 instances of long lines in gcc/*.[chly] at the moment. Only a few are in generated code.

I was also under the impression that one should not use tabs in GCC programs. Again I could find no authority for this point (over a hundred thousand instances of this, so maybe I made that one up).

I also note that the spacing requirement is only a recommendation.

    x = y + z;
rather than

The comments I received about spacing suggested that it was more than that!
