The maximum number of characters on a single line passed to the shell
(CLI=command line interface). It is set at compilation time and it turns
out to be hard to discover. It is probably related to the pipe size (bash
manual, ulimit -p -- says 8*512 bytes = 4kBytes here). If you try to pass
a longer command line it will be flagged as an error. Additionally, under
certain circumstances you can cause bad things to happen (as in, wrong
parameters passed to the next command) if you do this in a script and do
not check for errors. When something like *.pgn expands in a directory
with several hundred files you will exceed this limit. The error that
should be returned is E2BIG (see /usr/include/asm/errno.h), but in reality
it is something else like 'command line too long'.

Speaking of which, what is ENOANO (comment is 'no anode' ?! i.e. cathode
only, or ?!)
