advice on marking strings in bash scripts

[Eric Blake]

http://www.gnu.org/software/gettext/manual/gettext.html#xgettext-Invocation
doesn't mention 'xgettext -L Shell' as a valid option, but xgettext
--help does (I'm using xgettext 0.18.1).

Meanwhile, I'm trying to figure out how to mark strings for translation
in a shell script.  According to
http://www.gnu.org/software/gettext/manual/gettext.html#bash, use of $""
in bash is discouraged because bash mistakenly re-interprets translated
contents, allowing a translator to inject arbitrary shell commands.
Besides, since $"" is a bash-ism, when porting a script to POSIX sh
(such as dash), you'd have to go through gettext(1) anyways.

But the documentation for xgettext wasn't very clear on what it looks
for when using -L Shell mode.  Is it only picking up bash's $"", or does
it also look for 'gettext "string"' patterns when figuring out which
strings to mark?
