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.

The @code{error} function uses the @code{program_name} variable, but
does not depend on the @code{progname} module.  Why?  Because
@code{error} is released under the LGPL, whereas @code{progname} is
GPL.  RMS does not want additional baggage accompanying the
@code{error} module, so an LGPL user must provide their own
replacement @code{program_name}, and a GPL user should manually
specify using the @code{progname} module.

Additionally, using the @code{progname} module is not something that
can be done implicitly. It requires that every @code{main} function
be modified to set @code{program_name} as one of its first actions.
