Replace line feed in input line by null character

As result of a modification in logging (adding a line feed),
many changes had to be made in different places of cct.cpp.
However, one missed the line feed in input to cct.
As result of missing this, the output from cct showed a
superfluous empty line after each output line, but only if
the corresponding input line ended with comment.
Replacing the LF in the "comment" string (present if the
input line ended with comment) by a null character ('\0')
solves this issue.

Modification in logging?
