That's quite a style deviation from out norm in the commit log
messages, don't you think (see "git log --no-merges -100", for
example)? State the problem you are attempting to solve first, and
explain the solution to the problem, in separate paragraphs for
readability, perhaps like this:
There are routine tasks translators need to perform that can
be automated.
Help them to
(1) initialize or update the message files;
(2) check errors in the message files they edited;
(3) check errors in their commits; and
(4) review recent updates to the message template file
they base their translations on.
by adding a helper script.

Is there any bash-ism in this script? Otherwise please start this
with "#!/bin/sh" to allow people who do not use bash to get involved
in the project.

Style:
usage () {
In general, it is safe to mimic the style "git-am.sh" is written in,
although some crufts seem to have slipped in with recent updates.

Style: unless you have substitutions ($var etc.) inside the here
text, please quote the end token to make it clear that readers do
not have to scan and look for what is substituted, i.e.
cat <<-\END_OF_USAGE

Will we later regret that we didn't give a command word for this
one? Two common sources of such risks are:
(1) it turns out XX.po matches the pattern we would want to use as
a command; and
(2) it turns out "init/update" is not the most often used action.
I do not think (1) is likely. I do not think anybody can decide
about (2) at this point yet.

Do you really want the blank line output at the end?

That sounds like a blatant bash-ism to me.

Style:
if test $# = 0
then
ls *.po |
while read f
do
...
Also indentation is done with HT, not runs of SP.

Ah ;-) show_pot_update_summary() can be written so that this script
does not have to rely on bash-ism at all, as you are going to use
Perl anyway.

I am not sure if the protection these checks offer is worth the
complexity of the script, but it is primarily to reduce back and
forth between the l10n coordinator and the language teams, so I
won't complain.

I prefer not to see scripts forcing author's personal preference.
Especially, wouldn't ts=4 make it hard to avoid indenting with runs
of spaces by mistake?
