Create a full loop of documentation for rclone about, backends overview
and individual backend pages.
Discussion:
https://github.com/rclone/rclone/pull/4774 relates
Previously pull was requested, in part, under ref
https://github.com/rclone/rclone/pull/4801
Notes:
Introduce a tentative draft see-link format the end of sections to try
rather than lots of in-para links.
Update about.go incl link to list of backends not supporting about.
In list of backends not supporting about, include link to about command
reference.
I appreciate there may be decisions to make going forward about whether
command links should be code formatted, and using proper pretty url
links, but I have fudged that for now.
Update backend pages that do not support about with wording used
previously for ftp - it is in passive voice but I can live with it. (my
own wording and fault). The note is applied to a limitations section. If
one does not already exist it is created (even if there are other
limitations with their own sections)
This means the feature can be disabled by setting the time to 0.
This also logs the HTTP status for analysis purposes.
Thanks Felix Bünemann for extensive testing and data collection.
Shorten the URL to be used by the user and automatically use the
returned code by the server. The browser is opened on
`http://(bindaddress)/auth`, and redirected to the actual URL. When
the code is returned it is automatically inserted, instead of
requiring a copy+paste.
This is also a workaround for the "open" package, which escapes "&"
wrongly on Windows, so the opened URL's are invalid.
