[Gretl-devel] Feature request: vertical line for 'suggested' line length

Dear all, from time to time I use the IntelliJ IDEA editor which has an option to assist the user to follow the PEP8 Python coding guidelines. A tiny but helpful feature is the vertical line in the editor indicating the suggested maximum line length (which is 79 characters). I think also the Matlab editor has a similar indicator line. I find this quite useful for improving code readability. What do you think? Best, Artur
