Commented statements inside actions

[bottle2]

I dunno what is bug and what needs to be clarified in documentation.

I'll just share some experiments. here follows a MSYS2 session:

~/downloads $

haha "Android". I mean specifically Termux:

~/downloads $ uname -a
Linux localhost 4.19.191-g7dd98df8b4b4 #1 SMP PREEMPT Fri Mar 29 17:48:13 CST 2024 aarch64 Android

anyway, I don't really expect anything from this issue, just fixing funny warnings because I wrote a lot of Ragel before trying to compile for the first time
