flag 0 == keep line terminator on and allow continuation
1 == discard line terminator and don't allow continuation
Call with flag == 0 to read a command from a TAKE file;
Call with flag != 0 to read a line from a dialing or network directory.
In both cases, trailing comments and/or trailing whitespace is/are stripped.
If flag == 0, continued lines are combined into one line. A continued line
is one that ends in hypen, or any line in a "block", which starts with "{"
at the end of a line and ends with a matching "}" at the beginning of a
subsequent line; blocks may be nested.
Returns:
