Fix handling of quotes in testsuite artifact name

[GitMensch]

Looks good to me. Just a note: One could also get it directly out of configure.ac (note: the code below is not necessary portable as it uses a GNU grep extension -A, your version isn't portable because of the used cpp flags either) - the biggest benefit is that this can be done before running configure. Working since GnuCOBOL 2.2rc (not with earlier versions, but every one after, too):

grep "AC_INIT(" -A1 configure.ac | grep -v AC_INIT | sed -e 's/.*\[\(.*\)\].*/\1/'

Indeed. Or even with one less call to sed :-)

grep "AC_INIT(" -A1 configure.ac | sed -e '/AC_INIT/ d; s/.*\[\([^]]*\)\].*/\1/'

Anyways, we may assume portability is less of an issue on this CI.

Using modifiers also allows a match that works also back to OpenCOBOL (needing both GNU grep and GNU sed):

grep "AC_INIT(" -A1 configure.ac | sed -e ':nl;$!N; s/.*\[\([0-9][^]]\+\)\].*/\1/'

:-)

Oh full GNU sed is available, we can probably even avoid grep ;-)

sed -e '/AC_INIT(/ {z; N; s/.*\[\([^]]*\)\].*/\1/; t}; d' configure.ac
