Hi,
trying out v.net.path on yesterday's GRASS 7 OSGeo4W, the command runs
through properly (correct result) but raises then an error:

Would someone mind fixing the code to generate a more meaningful error
message when --interface-description fails (e.g. when the resulting
string is empty or consists solely of whitespace)?
I wonder where the error comes from... happens on Linux as well. Perhaps
the pipe | is causing it?
the problem is echo command because when you call 'echo
--interface-description' you get (surprisingly) '--interface-description'
(not error like any other bash command would raise). For other bash
commands (e.g. ls) you get (after ls output):
Unable to fetch interface description for command 'ls'.
Details: ls: unrecognized option '--interface-description'
Try `ls --help' for more information.
Please try r56388, there should be no error. But on Linux, pipe does not
seem to work as expected, anyway.
