[PATCH] gitsubmodules: add '--recurse-submodules' for 'ls-files'

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

`git ls-files` was never taught to respect the `submodule.recurse`
configuration variable, and it seems it is too late now to change that
[1], but still the command is mentioned in 'gitsubmodules(7)' as if it
does respect that config.

Adjust the call in 'gitsubmodules(7)' by adding the
'--recurse-submodules' flag.

While at it, uniformize the capitalization in that file, and use
backticks instead of quotes for Git commands and configuration
variables.
