[gentoo-dev] [PATCH bash-completion-r1] Introduce get_bashcompdir() to obtain bash-completion dir.

[Michał Górny]

Some ebuilds need to explicitly override bash-completion directory in
build system due to build systems having default non-matching Gentoo (or
rather Gentoo having bash-completion dir not matching anything else).

It's better to have a function to obtain that directory rather than for
ebuilds to hardcode it.
