---------------------------------------------------------------------- 
The read2 API call uses an ast_str dynamic buffer structure for the result,
instead of relying on a static buffer passed into the function.  This
allows the buffer to start out much smaller and to grow as necessary, which
is more memory-efficient for the common case, but also allows much larger
values to be processed in the exceptional case.

My suggestion for the arguments would be:
FILE(name,[L]offset,[L]length,file-format),
such that prefixing the offset with the 'L' character specifies the offset
is to be interpreted as a line number, and that prefixing the length
argument with an 'L' character specifies the number of lines to be read.  I
agree with your specification of the file-format, though, possibly, the
default should agree with the platform (i.e. on Cygwin, the default should
be 'dos').
