 In the course of updating firefox-x11-devel, I wanted reinplace commands
 that look like this (modulo the new option):
 {{{
     reinplace -u -E "s:(libplayback-1).so.0:${prefix}/lib/\1.dylib:" \
       ${worksrcpath}/modules/plugin/base/src/nsPluginNativeWindowGtk2.cpp
 }}}
 where the \1 copies the library name into the replacement text.

 They work fine in sed, but did not work in macports because \1 is a tcl
 escape sequence for control-A.

 This patch provides the -u option (shown above) to convert control-A to
 control-H into \1 to \7, assuming that they are the remains of escape
 sequences, enabling the command in the Portfile to be tested by copy-
 pasting into command-line sed without a lot of editing.
