Not to say whether or not this should be changed, but FYI the 79 comes from this set of facts: * Traditional terminals are 80 chars wide * Editors and viewers that do line-wrapping use the last character of the line to specify whether there was a wrap, otherwise you can't tell if the line is wrapped or there's a newline. So a line that is exactly 80 characters long would look like this in such a viewer: this line...is 80 chars lon\ g and this isn't Hence the restriction to 79 chars to avoid that wrap. Also, some kind -of-broken terminals used to automatically scroll the window if you wrote a character to the bottom-right-most character (line 24 / char 80). -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
