I'm tracking down why gnulib-tool no longer updates license headers correctly for me, and it boils down to me upgrading sed recently, and that gnulib-tool invokes sed with --posix. This works:
j...@mocca:~/src/libidn master$ echo 'version 2 '|sed -e 's/version \(2\|2\.1\)\([ ,]\)/version 3\2/g' version 3 But adding --posix makes it fail: j...@mocca:~/src/libidn master$ echo 'version 2 '|sed --posix -e 's/version \(2\|2\.1\)\([ ,]\)/version 3\2/g' version 2 I'm using GNU sed v4.2 from debian testing. I suspected the final g parameter to s/// but removing that didn't help. Is this a sed bug? It kind of seems like it, but I'm not certain. Thanks, /Simon
