curl/scripts/maxline
Daniel Stenberg badbd4eb46
manpage: ensure a maximum width for the text version
... using the new script 'maxline' to which we specify the maximum
number of columns we allow any single line to be, or it will cause an
error.

Starting out with a max width at 100 columns.

Bonus: shorten the long line in the --ipfs-gateway section.
