Drop trailing whitespace. On behalf of me.

PR/33054: Nicolas Joly: id(1) sometimes report a duplicate group when a user
is not specified. This is because it prints getgid() and getgroups(). If the

id(1) didn't check the return value of getgrouplist(3) and used memory
outside the group array in the case that a user is member of more than
_SC_NGROUPS_MAX groups.

Closes PR bin/7592 by cgd.

it look like what Solaris and Linux use (comma but no space between items).

Make this compile again, and fix some whitespace lossage.

Replace groups and whoami sh scripts with hard links to id.

Add "-p" usage line.

Add { and } to shut up egcs. Reformat the more questionable code.
