Commands for die-hard SED programmers

In most cases, use of these commands indicates that you are probably better off programming in something like PERL. But occasionally one is committed to sticking with SED, and these commands can enable one to write quite convoluted scripts.

`: label'

[No addresses allowed.] Specify the location of label for the b and t commands. In all other respects, a no-op.

`b label'

Unconditionally branch to label. The label may be omitted, in which case the next cycle is started.

`t label'

Branch to label only if there has been a successful substitution since the last input line was read or t branch was taken. The label may be omitted, in which case the next cycle is started.
