If you're looking at strfmon in general: there are, or were, cases where
left-justification ('-' flag) is handled improperly.  (Some Austin Group
drafts were unclear in the specification; I submitted reports of the
problem with the drafts and the specification was clarified to follow the
cleaner interpretation of Solaris rather than that of glibc.  I don't
think glibc has subsequently been fixed to follow the specification.  The
drafts used to say "all fields are left-justified" and this was fixed to
"the result of the conversion is left-justified", and it is now specified
that this flag is ignored unless a field width is specified.  Testcases in
the examples in the standard
<http://www.opengroup.org/onlinepubs/007904975/functions/strfmon.html> and
in the original Austin Group comments
<http://www.opengroup.org/austin/docs/austin_77r2.txt>.)
