And describe it in documentation. We've introduced
sectalign in 2.09rc series and have to provide an
ability to steer this feature.

Since %rep counter is a 64 bit signed integer we have to use some
"maximum possible value" limit (upper bound) otherwise there may be
a situation when %rep counter is 0 or even negative while user
has been passing big positive integer value.

Two fixes:
1. Optimization of [bx+0xFFFF] etc
0xFFFF is an sbyte under 16-bit semantics,
so make sure to check it right.
2. Don't optimize displacements in -O0
Displacements that fit into an sbyte or
can be removed should *not* be optimized in -O0.
Implicit zero displacements are still optimized, e.g.:
[eax] -> 0 bit displacement, [ebp] -> 8 bit displacement.
However explicit displacements are not optimized:
[eax+0] -> 32 bit displacement, [ebp+0] -> 32 bit displacement.
Because #2 breaks compatibility with 0.98,
I introduced a new optimization level: -OL, legacy.
Allow non-identifier characters in the name of environment variables,
by surrounding them with string quotes (subject to ordinary
string-quoting rules.)

We still miss Chuck, but I don't think we can really say anymore we're
doing this particular release in his memory.
Requiescat in pace, our friend.

Make -Ox the default; it's the optimization level expected by most
users, and it is clearly still causing confusion that it has to be
specified manually.

inslist.src is an intermediate file, it should be in "make clean"
rather than "make spotless"; otherwise it ends up in the xdoc tarball.

Due to previous commit empty line was occasionally
removed which make text harder to read. Restore it.

We've a problem in supporting [i]rmacro, exitmacro
facilities at moment.
In a sake of not holding new NASM release any longer these
directives are just marked as being "forbidden".
This allow us to not squash much changes in current source
code base but remain on a safe side same time.

This reverts commit 3012d5d430.
nasm64developer pointed out that we still have this
limit in label.c (IDLEN_MAX).

We always allocate enough memory to hold identifiers
with any length. So lets remove restriction from

It isn't just invalid UTF-8 sequences that are affected; it is in fact
any high-bit bytes (we don't ever try to construct UTF-8 characters,
just deconstruct them.)
