Does this fix the recent problems people were having with sed? The examples I could dig up on the web that use the `N' command work properly with this change (same as they do on -DP1).
Here are a few of the examples that are fixed: (from http://www.faqs.org/faqs/editor-faq/sed/) # 10. Delete all CONSECUTIVE blank lines from file except the first. # This method also deletes all blank lines from top and end of file. # (emulates "cat -s") sed '/./,/^$/!d' file # this allows 0 blanks at top, 1 at EOF sed '/^$/N;/\n$/D' file # this allows 1 blank at top, 0 at EOF # 12. Delete all trailing blank lines at end of file (only). sed -e :a -e '/^\n*$/{$d;N;};/\n$/ba' file # 13. If a line ends with a backslash, join the next line to it. sed -e :a -e '/\\$/N; s/\\\n//; ta' file If this change doesn't fix the problems, please give me small and simple sed scripts that demonstrate the incorrect behaviour.
