The links were broken due to:
1. Incorrect quotes (' instead of " for module links and occasionally
vice-versa).
2. Changes in the name of the "target" module not reflected in the
"source" docs.
3. Typos to begin with.
4. Use of `<foo>` in the docs is rendered as just `foo` with a link to
`/foo`.
5. Similarly for `"Foo"` if it starts with a capital letter (and hence
could be a module).
6. Markup inside `@` code blocks still being applied.
e.g. `@M-<arrow-keys>@` is rendered as `M-arrow-keys` with a spurious
hyperlink from arrow-keys to `/arrow-keys`, which is confusing.
Three links from XMonad.Util.Run have been removed outright, since
they're no longer examples of the usage of 'runProcessWithInput'.
WmiiActions has been gone since 2008, while XMonad.Prompt.Directory
and XMonad.Layout.WorkspaceDir haven't been using
'runProcessWithInput' since 2020 and 2012, respectively.
In some cases the `<foo>` were surrounded with @, especially in the
case of key definitions, for consistency. (This wasn't done
everywhere, because it looks ugly in the source.)
MoreManageHelpers has never been in xmonad-contrib. ManageHelpers
seems to fill the expected role.
In the case of the module description for X.H.ManageDebug the quotes
were simply removed because none of the likely options to make the
link work were successful.

-- A module for spawning a command once, and only once. Useful to start
|
|
-- status bars and make session settings inside startupHook. See also
|
|
-- "XMonad.Util.SessionStart" for a different and more flexible way to
|
|
-- run commands only on first startup.
