I'll assume this is coding exercise, and set aside the questionable need
for this utility.

- Line 28. Error messages like this should go to stderr. Stdout should
contain the correct result, or nothing. Adhering to this rule will
make the program more suitable as a filter in a pipeline.

- What guarantee do you have that the input file won't contain any lines
with length > LINE_MAX? As far as I know, that's an arbitrary number,
and there is no intrinsic limit on the length of the lines in a Unix
text file.
