Yeah, I obviously looked at the page I quoted that describes
what's in and what's not in BRE definition ;-)
But in practice, I do not recall ever seeing an older sed that
did not understand one-or-more \+ *and* understood \{1,\}. Do
you?
I had to deal with autoconf (hence various flavours of UNIX
implementations) in my previous life, but that was an ancient
history (back then the effect of SysV vs BSD war was still
felt). As a maintainer of a public project I understand you
have to deal with the current set of variations, and you might
know better than me about the current portability situation.
