	* linux-fork.c (_initialize_linux_fork): Rename "delete-fork"
	command to "delete fork" (no hyphen), compatible with other
	"delete" commands.
	(info_forks_command): Accept a fork ID argument, for info
	on a single fork.  Report if no matching forks.

2006-04-26  Michael Snyder  <msnyder@redhat.com>

	* gdb.base/multi-forks.exp: Modify patterns for "run to exit",
	which may have to consume output from other forks.
	Add tests to make sure that "delete fork" succeeded.

2006-04-27  Michael Snyder  <msnyder@redhat.com>

	* gdb.texinfo (delete-fork): Command renamed to "delete fork".
