Locale-related test failures

[Gavin Smith]

I've got test failures in the tp/t directory. They appear to be
related to translations:

$ diff t/results/misc_commands/many_lines.pl*
1773c1773
<     'error_line' => ':29: warning: unrecognized encoding name
`US-ascii encoding name\'
---
>     'error_line' => ':29: warning: unrecognised encoding name `US-ascii 
> encoding name\'
1778c1778
<     'text' => 'unrecognized encoding name `US-ascii encoding name\'',
---
>     'text' => 'unrecognised encoding name `US-ascii encoding name\'',
$

The translation for British English has changed "unrecognized" to
"unrecognised".

All these fail:
FAIL: t/08misc_commands.t 15 - many_lines errors
FAIL: t/08misc_commands.t 132 - invalid_documentencoding errors
FAIL: t/50value.t 123 - value_in_invalid_documentencoding errors
FAIL: t/60macro.t 501 - macro_in_invalid_documentencoding errors
FAIL: t/80include.t 72 - macro_and_commands_in_early_commands errors
FAIL: t/info_tests.t 402 - unknown_encoding errors

Have there been any recent changes that would make error messages be
translated in the test suite? (I haven't run the test suite for about
the last two weeks.)
