Bugs are revealed in using the compiler, not in reading the documentation.

Yes, please do.  They are documented; you can work around them, or (if you
have source) you can fix them.

Converting to all lowercase is an advantage?  Try implementing a full-function
ls (an esoteric command, I give you :) with all lowercase options and without
arbitrarily assigning letters to options.  I like single-letter flags, thank-
you.

I agree.  It is definately a nuisance to have to worry about all the bugs
that lint could uncover.

If you want to limit yourself to DEC terminals, then go ahead - hard code
the DEC control sequences into your programs.  Don't limit us to only those
terminals. /etc/termcap (or terminfo) is a feature, not a disadvantage.
