[PATCH 3/7] add a test for semantic errors in config files

[Tanay Abhra <tanayabh@gmail.com>]

Semantic errors (for example, for alias.* variables NULL values are
not allowed) in configuration files cause a die printing the line
number and file name of the offending value.

Add a test documenting that such errors cause a die printing the
accurate line number and file name.
