xgettext incorrect reports non-ascii characters

[Morten Welinder]

1. xgettext report non-ASCII characters where none are used, see below.
   (The string uses four plain ASCII characters: backslash, x, e, and f.
   That is different from using one non-ASCII character.)

2. xgettext has no options for turning that warning off.  ASCII is not
   the only sane base encoding to use -- another is UTF-8.  It might
   be that some translators will have trouble, but that cannot be
   helped.

Note: I can ignore the warning just fine, but it's going to upset
translators for no good reason.

xgettext: warning: The following msgid contains non-ASCII characters.
                   This will cause problems to translators who use a character 
encoding
                   different from yours. Consider using a pure ASCII msgid 
instead.
