[pacman-dev] [PATCH v2 2/6] makepkg: devel_check(): determine vcs

[dgbaley27 at 0x01b.net]

From: Matthew Monaco <matthew.monaco at 0x01b.net>

EDITS:
  - user arithmetic contexts for integer comparison
  - use the regex comparison operator to test array membership

Rather than prioritizing an arbitrary VCS, collect all development
directives. If there is more than one, use the package name as a hint.
If that doesn't work, abort.
