[patch, committed] [4.3 Regression] corner case continuation line

[Jerry DeLisle]

This patch committed as obvious and simple.

I have not found a way to add a test case because any dg-error directives in a 
comment will prevent the error from occurring.  This is because we do free-form 
comment elimination elsewhere so printable characters in comments are seen in 
load_line.

A future enhancement will be to move free-form comment elimination down into 
load_line.

Committed revision 131371.
