Options:

a) Tell the customer that you are sorry that glibc does not at present offer
what he expects, and that we are unable to fix this ourselved without breaking
compatibility with every other glibc-based distribution. One possible
customer-side workaround is to replace SP with NBSP (0xa0) before sorting. NBSP
does already seem to get sorted in the way in which the customer expects SP to
be sorted.

b) Patch in /usr/share/i18n/locales/iso14651_t1 the line

  <U0020> IGNORE;IGNORE;IGNORE;<U0020> # 32 <SP>

to something like

  <U0020> <U0020>;<BAS>;<MIN>;IGNORE

to make SP sort like NBSP does already

WARNING: This obviously breaks compatibility with other Linux distributions.

c) Fund a proper research project aimed as cleaning up the mess that the
collation implementation and configuration is at present in glibc and POSIX,
possibly also investigating user needs and developing a new API for customizing
the sorting order at run-time via environment variables and/or new library
calls.

The reported propblem is only one symptom of the fact that the collating code
(and perhaps even the underlying POSIX spec!) is not really finished and is at
present not properly maintained.

Option c) is perhaps what really should be done, but needs far wider discussion
(beyond Novell) and escalation to management, because someone will have to
spend many weeks (if not months) on sorting this entire issue out properly.
