not optimal from a performance standpoint since the write buffer is
not necessarily be filled up when the inflate rountine reached the
end of input buffer and it's not the end of file.
This problem gets uncovered by trying to pipe gunzip -c output to
a GEOM device directly, which enforces the writes be multiple of
sector size.

the name of the typescript file.
+ Add the 'command' argument (if supplied on the command line) to the
typescript file. This creates a more complete typescript when invoked
this way - more equal to invoking script without supplying the 'command'
argument.
bitwise parameters (e.g. mmap), print the syscall parameter value first.
The resulting output looks like the %b specifier of printf(9).
Before:
mmap(0,0x8000,PROT_READ|PROT_WRITE,...
After:
mmap(0,0x8000,0x3<PROT_READ|PROT_WRITE>,...

Idea from: freebsd-arch/2006-April/005116.html
Octal escape sequences are expanded to bytes, not characters, and multiple
are required for a multibyte character.
The valid escape sequences in %b strings are slightly different from the
escape sequences in the format string.
- Imply -h if single file is grepped, this is the GNU behaviour
This is already done by code above the change and have caused a regression
since this instance of code does not check Hflag.

instead of stdio. This gives BSD grep a very big performance boost,
its speed is now almost comparable to GNU grep.

All these functions and variables are local to this compilation unit, so
there is no reason why we shouldn't mark them static. This slightly
reduces the binary size.
former may be safer but in this case it doesn't add extra
safety [1]
- Fix -w option [2]
- Fix handling of GREP_OPTIONS [3]
- Fix --line-buffered
- Make stdin input imply --line-buffered so that tail -f can be piped
to grep [4]
- Imply -h if single file is grepped, this is the GNU behaviour
- Reduce locking overhead to gain some more performance [5]
- Inline some functions to help the compiler better optimize the code
- Use shortcut for empty files [6]

uname and gname weren't overwritten, so the
disk restore would use those to lookup the
original uid/gid again. Clearing the uname
and gname prevents this.
