Summary:                    The alternatives --set option fails for
sudo/sudo_ldap
Description: 
With sudo and sudo_ldap installed the alternatives --auto sudo makes a
selection, but using the --set option one is unable to select a specific
alternative.

# alternatives --display sudo
Installed alternatives for sudo are:
/opt/csw/bin/sudo     sudo     /opt/csw/bin/sudo.ldap     60
/opt/csw/bin/sudoedit sudoedit /opt/csw/bin/sudoedit.ldap
/opt/csw/bin/sudo     sudo     /opt/csw/bin/sudo.minimal     50
/opt/csw/bin/sudoedit sudoedit /opt/csw/bin/sudoedit.minimal

# alternatives --set sudo /opt/csw/bin/sudo.minimal
Error: no installed match found for sudo /opt/csw/bin/sudo.minimal

The issue is with: 

297          check=`egrep -l "^[^ ]* $1 $2 " $PRIORITIESDIR/*`

This assumes a single space between fields.  Given the lack of
documentation for this file format it is reasonable that one would assume
the unix norm of one or more spaces between fields.  On fix for this would
be:

check=`egrep -l "^[^ ]* [ ]*$1 [ ]*$2 " $PRIORITIESDIR/*`

As an alternative you may wish to also add support for tab separators. 
Man page / documentation would be appreciated.

I chose to submit this as a alternatives bug rather than a sudo* bug
because I believe alternatives should support this functionality.
