/^;/ { H ; $ bl ; b }

In case you are interested in writing the most portable sed possible, using a semicolon after a branch command is not portable. With that syntax, the script may not work with most implementations. If portability is desired, it's best to use a newline after each branch command.

For fun, here's a sed solution which does not use branching. It's a bit shorter but not as clear as your approach (and probably not as efficient, since it unconditionally executes the substitute command for each line read).

Code:
sed -n '/^;/H; x; s/\n;/;/; x; /^;/!{x; 1!p;}; ${x;p;}'

rpccp_remove_profile

remove profile(1m)														remove profile(1m)

NAME

       remove profile - Removes all profile elements and the profile from the specified name service entry

SYNOPSIS

       rpccp remove profile  profile-entry-name [-s syntax]

OPTIONS

       Indicates  the  name  syntax of the entry name (optional). The only value for this option is the dce name syntax, which is the default name
       syntax. Until an alternative name syntax becomes available, specifying the -s option is unnecessary.

ARGUMENTS

       name.

DESCRIPTION

       The  remove  profile  command  removes a profile (and all of its elements) from the name service database. The entry name of the profile is
       required.

   Privilege Required
       You need write permission to the CDS object entry (the target profile entry).

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLES

       The following  commands	run  RPCCP  and  remove  the  profile  named  /.:/LandS/anthro/molly_o_profile:  $  rpccp  rpccp>  remove  profile
       /.:/LandS/anthro/molly_o_profile

RELATED INFORMATION

       Commands: add element(1m), remove element(1m), show profile(1m)
