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.

A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. The @code{ctime} function need not be reentrant, and consequently is not required to be thread safe. Implementations of @code{ctime} typically write the time stamp into static buffer. If two threads call @code{ctime} at roughly the same time, you might end up with the wrong date in one of the threads, or some undefined string. There is a re-entrant interface @code{ctime_r}, that take a pre-allocated buffer and length of the buffer, and return @code{NULL} on errors. The input buffer should be at least 26 bytes in size. The output string is locale-independent. However, years can have more than 4 digits if @code{time_t} is sufficiently wide, so the length of the required output buffer is not easy to determine. Increasing the buffer size when @code{ctime_r} return @code{NULL} is not necessarily sufficient. The @code{NULL} return value could mean some other error condition, which will not go away by increasing the buffer size. A more flexible function is @code{strftime}. However, note that it is locale dependent.
