I tend to disagree, but that's really not important ;)

I do not know how to perform reliable memory benchmarks, but am pretty
sure that disabling gettext has no noticeable impact because localized
messages are not used at all with LC_ALL=C:
 $ strace -e open /usr/sbin/adduser --help 2>&1 > /dev/null | grep locale
 open("/usr/share/locale/fr_FR/LC_MESSAGES/adduser.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
 open("/usr/share/locale/fr/LC_MESSAGES/adduser.mo", O_RDONLY) = 3
 $ LC_ALL=C strace -e open /usr/sbin/adduser --help 2>&1 > /dev/null | grep locale
In GNU libc, gettext() returns its argument in this case (and also when
no msgstr was found), so there is no string copy.  If Locale::gettext
does the same (no idea whether this is true or not), gettext (with
LC_ALL=C) is very similar to
  *gettext = sub { shift };

Sure.  At the moment it did not yet reach my mirror, will look at it
later.  Thanks for taking care.
