`cargo fetch --offline` documentation directs user to use `cargo fetch --offline`

[larswirzenius]

Problem

The documentation for cargo fetch --offline (the manual page) includes the words "See the cargo-fetch(1) command to download dependencies before going offline."

This seems needlessly self-recursive. In fact, I'm not sure why cargo fetch offers an offline mode, but maybe it's useful in some case.

Steps

No response

Possible Solution(s)

Drop the sentence directing the user to cargo fetch --offline from the description of cargo fetch --offline. I realize this is boilerplate shared with all cargo subcommands that have an --offline option, and I don't know if the template system used allows a way to exclude parts for specific commands.

Notes

This is really not a big issue. I'd be happy for you to ignore this until all other issues have been resolved.

Thanks for the report. The template language is handlebars, and it supports conditional templating.

For each command there should be a command variable available, so guess we can check if it is fetch and exclude the self-referential part.

cargo/src/doc/man/cargo-fetch.md

Line 2 in ac6bbb3

{{~*set command="fetch"}}

Though I am unsure if it is worth the complexity to have an additional condition there. Seems no harm to me to have self-referential, so tag P-low but feel free if pick up and fix it.

it seems an another document issue, I'd like to take a shot.
