Subject: bug#12372: [FYI 2/2] {maint} coverage: better exposure for automake bug#12372 (tags-related)
Date: Tue, 11 Sep 2012 11:46:07 +0200

Alas, in contrast with what is said in the commit message of previous
commit 'v1.12.3-14-g94b7b8e', that bug is still present also in the
current maint branch (which will become automake version 1.12.4); it
is just that it only triggers when a _SOURCES variable contains only
files with custom extension.

* t/tags-pr12372.sh: Extend.
* t/list-of-tests.mk: Add it.
