Don't try to trim trailing blanks here -- it's not possible
because we don't know where the field begins.
Properly distinguish between cases where TAB character is specified
and when the default is used.
(trim_trailing_blanks): New function.
(findlines): Call it.
(keycompare): Likewise.

(limfield): Fix bug that made field specs like -k1.5 return a
pointer into LINE beyond the first field.
Rewrite to properly ignore trailing blanks.
Replace unnecessary loop with if-else.
(main): Don't decrement T2 corresponding to `x' in field specs like -ku.v,w.x.

[!INT_MAX]: Define.

(cleanup_fatal): New function. Call cleanup, then exit.

then repost caught signal.

Add const attribute to lots of parameters.

Erik Bennett <bennett@cvo.oneworld.com> reported that this is
necessary on BSDI systems. And if offset doesn't fit in a long,
then try using lseek instead.

(xrealloc): Likewise.

Update callers.

the same and the file descriptors correspond to stdin and stdout.
This is necessary on at least Digital UNIX (aka OSF1) 3.2C.
Otherwise, running `cat << X > $$' would fail with `cat: -: input
file is output file'. From Jarkko Hietaniemi <jhi@epsilon.hut.fi>.
