RFE: upgrade 'sed' RE's to include perlre syntax.

[Linda A. Walsh]

Both simple atoms such as "\d" for [0-9] or "\S" for non-space characters
are supported in awk and have been added to grep with the -P switch.

Would it be possible to add a -P type switch to 'sed' so that
pcre compat RE's could be used?

Yes, indeed part of the work is already done and part of the GNU sed
tarball (search for REG_PERL). Though the option was -R, not -P.

I want to release a new version of sed this August (it is time!) and I
would love to include this functionality on it. I think it is not too
late to use -P instead of -R, to keep some uniformity with the other
tools.

I can try... :)

Jose, in the meanwhile can you update gnulib in the sed repository?

Awesome. I don't have a heavy preference on -R v. -P, but trying to
keep similar
function switches the same between tools would be a bonus.

It is REALLY a headache remember what the switch is to specify the
"delimiter"
char in sort, vs. cut, et al...I seem to always pick the wrong one.
