Those fifos are accessible during %sh{...} blocks, the command fifo
executes commands written to it once the write end side is closed
(multiple open/write/close sequences are supported), the response
fifo is a simple helper fifo available to write response back to
the shell process
An example use of this feature is to request some list options
content from without being limited by the environment size:
```
%sh{
echo "echo -to-file $kak_response_fifo -quoting shell -- %opt{some_list}" > $kak_command_fifo
eval "set -- $(cat $kak_response_fifo)"
}
```
Gentoo has a wiki page documenting Kakoune installation. The method given here ("emerge kakoune") will not work on a default Gentoo installation, as Kakoune is currently in the Testing branch rather than in the Stable branch. A link to the documentation explaining how to install Kakoune on Gentoo seems pertinent.
If a %sh{} script refers to any variables multiple times they are all multiply
included in the environment. Example: if a %sh{} invocation refers to
${kak_buffile} 5 times, the environment will have "kak_buffile=..." repeated 5
times and so on. This repetition happens for each multiply used variable that
is passed into the environment.
The variable should, of course, be only passed into the environment once. This
commit should fix this issue.
