[PATCH 0/3] {testsuite-work} Test automake-provided shell scripts (those in `lib/') also with $SHELL, not only with /bin/sh

[Stefano Lattarini]

Follow-up from thread:
 <http://lists.gnu.org/archive/html/automake-patches/2011-06/msg00016.html>

The aim of this patch series is to increase coverage in the "unit tests"
for the Automake-provided tests scripts  (i.e., in those tests that run
said scripts directly, outside Automake-generated Makefiles, and check
their outputs, exit statuses, error messages, postconditions, etc).

Currently, such "unit tests" only use the default system shell `/bin/sh'
to run the checked scripts; after the series is applied, they should be
transparently extended (wrapped, in fact) to use *also* $SHELL to execute
the checked script.

I will push this series in 72 hours if there is no review by then.

Regards,
  Stefano
