[pacman-dev] Bad strings for translation

[Dan McGee]

Noticed the following today in makepkg, we should be using warning()
calls instead so this same word isn't translated over and over:

+
+msgid "Warning: Unknown public key"
+msgstr ""
+
+msgid "Warning: the key has been revoked."
+msgstr ""
+
+msgid "Warning: the signature has expired."
+msgstr ""
+
+msgid "Warning: the key has expired."
+msgstr ""
+
