annotate lib/unistr/u32-prev.c @ 12518:b5e42ef33b49

update nearly all FSF copyright year lists to include 2009 The files named by the following are exempted: grep -v '^#' config/srclist.txt|grep -v '^$' \ | while read src dst; do test -f "$dst" && { echo "$dst"; continue; } test -d "$dst" || continue echo "$dst"/$(basename "$src") done > exempt git ls-files tests/unictype >> exempt In the remaining files, convert to all-interval notation if - there is already at least one year interval like 2000-2003 - the file is maintained by me - the file is in lib/uni*/, where that style already prevails Otherwise, use update-copyright's default.
