Summary: DOS Style line ending brakes display output

Initial Comment:
DOS Style line ending brakes display output. The match is detected but not displayed. See the attached mock-up source tree. egrep for MYMAP_ the search matches '1' and '2' are not visible, but "operational". A better fix should run the characters of 'tempstring' , if there are non-displayable chars it should still display the file name, function, and line number, but replace the matched text with ellipsis.

Proposed change:
Index: display.c
