#1 Icomplete-0.3 does not work for some version of regex lib

[dearvoid]

On Redhat Linux 9.0, the regex function does not
support "\s" so icomplete does not work. For better
compatibility, use "[[:space:]]" or "[<space><tab>]"
instead of "\s".

The attached file is my patch file.

Thanks for the bug report.

Please try current cvs version, since it includes a
completely new handwritten include file parser.

However your problem with \s may also appear in other regex's.
