"command line" string not suitable for command line

[goddard@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.17134
ChimeraX Version: 0.7 (2018-08-01)
Description
Distance mouse mode gives an errror when two models open because the distance command that is generated does not produce proper atom specifiers -- the structure names is given.

This is a bug in the Atom.string(style = "command line") method.
