[vcsh] hook system for vcsh

[Dieter Plaetinck]

i like the concept and the general implementation looks compact and neat.

setting executable flag to make it become sourced seems weird.
especially because +x is not even needed if it's sourced.
i would say merely the fact that a file is stored within
$XDG_CONFIG_HOME/vcsh/hook.d/init/ qualifies it as a hook. nothing more
is needed. no +x flag.

inside the hook file, you can do logic like:
if [ "$VCSH_REPO_NAME" = "vcsh" ]; then... fi
the fact that hooks are sourced (vs executed) is very powerful, it
gives the hook access to everything going on within vcsh. (all vars,
all defined functions, etc)

what are foo and bar? different files, so the $VCSH_HOOK_D/init file sources those 2 files?
