Vim syntax: Allow `x86_64_v3` in $arch
Arch Linux RFC 2 added "x86_64_v3" as a (future) official Arch Linux build architecture, but vim is currently not happy when PKGBUILD
s have "x86_64_v3" in their $arch
array.
This adds "x86_64_v3" to the list of allowed pbArch
keywords as well as the various {source,depends,…}_$arch
to the list of srcInfoField
s for .SRCINFO
.
