I believe that the _only_ character that will allow a line
break|wrap is the space character Ascii 32.
Also the hyphen and the tab.
I checked every ascii possibility between 0 and 255 and got a strange
result. Add to the above these ASCII values, in decimal,
03
13
126
155
169
181
182
198
199
(a lot, but not all, of the box-building characters over 200)
I tested this in a file with overlong lines, then changing the value of RM,
and seeing where lines containing each character broke.
