Make PurplePluginProtocolInfo definitions consistent

Since we can't use C99 structure initialisers, we have to manually add
new NULL fields to all protocols whenever we extend the structure.

Make it slightly easier to script that, by making the current last
field (get_cb_alias) consistent in all cases. In particular, there's
no reason *not* to have the trailing comma, as most already do.

Now I can add a new field to the PRPL by doing something like this...

PROTOFILES=`grep -rl '[A-Za-z_][A-Za-z0-9_]*,[[:space:]]*/\* get_cb_alias \*/' libpurple/protocols/ `
sed '/\/\* get_cb_alias \*\//{p;s/[A-Za-z_][A-Za-
#!/usr/bin/env perl

# check_po.pl - check po file translations for likely errors
#
# Written by David W. Pfitzner dwp@mso.anu.edu.au
# This script is hereby placed in the Public Domain.
#
# Various checks on po file translations:
# - printf-style format strings;
# - differences in trailing newlines;
# - empty (non-fuzzy) msgid;
# - likely whitespace errors on joining multi-line entries
# Ignores all fuzzy entries.
#
# Options:
# -x Don't do standard checks above (eg, just check one of below).
# -n Check newlines within strings; ie, that have equal numbers
# of newlines in msgstr and msgid. (Optional because this may
# happen legitimately.)
# -w Check leading whitespace. Sometimes whitespace is simply
# spacing (eg, for widget labels etc), or punctuation differences,
# so this may be ok.
# -W Check trailing whitespace. See -w above.
# -p Check trailing punctuation.
# -c Check capitalization of first non-whitespace character
# (only if [a-zA-Z]).
# -e Check on empty (c.q. new) msgstr
#
# Reads stdin (or filename args, via <>), writes any problems to stdout.
#
# Modified by Davide Pagnin nightmare@freeciv.it to support plural forms

# TODO: This script needs to be able to handle Farsi's %Id flag for
# number format specifiers. More information on how it works, see
# http://www.gnu.org/software/hello/manual/gettext/c_002dformat.html
# It's possible someone has already made this change... look around
# for an updated version of this script.
