Seems like a place to use a patch file.

This works. Caveat emptor: || (empy RE) doesn't work and range seems to start 
on first line, not on its subsequent.

reinplace -E 1,/foo/s|foo|foo\\\n\\\tbar| file

I needed to add disabled/true to a startup item provided by a port's source.

Well the stack overflow answer says non-GNU sed doesn't support the 
single-command version, and needs a two-command version. reinplace doesn't 
support executing multiple commands. 

You could run a two-command sed manually (with system, not reinplace). Or maybe 
you can use awk, or an ed script. 

I can't remember anybody asking for this functionality (replace first 
occurrence) before, so that's why there isn't an easy way to do it. 

reinplace first occurrence

I checked portfile's man page and peaked at the source, but couldn't figure out 
yet, why these forms don't work.

In the meantime, I worked around it, but I'd still like to know how to do it.
