Subject: [PATCH 7/8] Fix test for presence of BASH_LINENO[0]

eval is not some sort of magical sandbox for executing code that might cause
the shell's parser to take exception. Render the test resilient by carrying
it out within a subshell. While at it, position the redirection so that
STDERR is, in fact, muted.
