I've uploaded a patchset to SourceForge that implements
	set decimalsign { <value> | {locale {<LOC>}}

My thought is that people can try this out and report back whether
there is a need to separate out the input and output locales.

By the way, it may be obvious but let me state it explicitly:

The existing `set locale` command only affects LC_TIME, the format used
for time/date strings.

The new command options to `set decimalsign` only affect LC_NUMERIC,
the format conventions used by the C library for scanf and printf.

Neither of these affects LC_CTYPE, which controls the character set
and font encoding.
