Subject: [PATCH] AK2: allow next blank line (" ") for replace_section and
 remove_section - sometimes it's difficult to anchor to specific end lines due
 to variations across ROMs, so allow the end line to be blank " " - note this
 will also remove the trailing blank line so for replacements a trailing \n
 should be added to maintain spacing; this should be pretty intuitive since
 you are including the blank line as the end line search
