space-separated paths

[Simon B. <ba...@ga...>]

Are there any good techniques for dealing with space-separated
paths in modules?  $INC_PATH is an example.  We have a
shell-specific solution but dealing with multiple shells
is harder and would seem to call for some new functionality
in modules itself.  You can't just use setenv because this causes
$INC_PATH to be wiped out when the module is unloaded.

TIA
