Included markdown files are not update with `mdbook serve`

[konstin]

Problem

Files included with {{#include path/to/file}} are not updated with mdbook serve, and it seems there is no option to manually add files to be watched.

In our (maturin), we include the readme as introduction page in the guide to avoid repeating the content from the readme.

Steps

1. git clone https://github.com/konstin/mkbook-watch-reproducer
2. mdbook serve guide and open the page in the browser
3. Edit installation.md. The changes are updated in the browser.
4. Edit Readme.md. The changes are not updated in the browser! You need to run mdbook build guide to rebuild them.

Possible Solution(s)

mdbook should watch included files, too, or add an option to manually include them. I tried extra-watch-dirs with .., with an absolute path and with the path to the directory, but to no avail.

I just tried it using mdbook v0.4.47 on Linux and the extra-watch-dirs worked for me. The pathes there should be relative to the root of your book. That is the folder where book.toml can be fount.

It is also important to put this configuration option in the [build] sections.

I just managed to waste half an hour by putting it in the [book] section as I was trying to check if this works. @ehuss , we really need to go forward with #1595, could you please review the first steps: #2622

@konstin, did you maybe also make the same mistake with the configuration?

Another issue: if the included files are in .gitignore then the watcher will also ignore them.
