sed -r not supported on on osx

[eaubin]

Running with gives

sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

The line is here. I think sed -E should work.

-E works in OS X, but then wouldn't it stop working on other platforms? -E is used in FreeBSD and Mac OSX, but FreeBSD has an -r alias, while OS X doesn't...

@waldyrious -E does work on both BSD and GNU sed AFAIK. I can't throughout test the code right now, though.

[waldyrious]

That would be great, but it doesn't seem to be the case. You may be thinking of lowercase -e which indeed works in both BSD sed and GNU sed.

Nice! So we could use -E, cool. And wow, the fragmentation :/
