Subject: maint.mk: ignore multi-line copyright in NEWS
X-Git-Tag: v0.1~4895
X-Git-Url: https://gitweb.git.savannah.gnu.org/gitweb/?a=commitdiff_plain;h=c4b45631bce0034e4433a9f421cf16fe803c51f3;p=gnulib.git

maint.mk: ignore multi-line copyright in NEWS

The old algorithm did not work for projects like m4 that used
long-hand copyright years that wrapped lines.  Meanwhile, this
change has no impact to single-line copyrights, like coreutils.

Changing the rest of the footer, such as bumping from GFDL 1.2
to GFDL 1.3, will still require the developer to rerun
'make update-NEWS-hash' to get the hash back in sync, but that
is probably less frequent.

* top/maint.mk (NEWS_hash): Add immunity to multi-line copyright.
