svn commit: r334565 - head/usr.bin/indent

[Piotr Pawel Stefaniak]

Author: pstef

New Revision: 334565
URL: https://svnweb.freebsd.org/changeset/base/334565

Log:
  indent(1): remove is_procname.
  
  It was a shorthand for checking if ps.procname is a non-empty string; the
  same can be done with ps.procname[0] which avoids the need for updating
  is_procname after every call to lexi().
