emulate -A and -h ls flags

[wrboyce]

-A - shows dotfiles but not . and ..
-h - shows "human readable" file sizes

[sattellite]

For implement -h flag needs add that code before line 202:

     if [[ $1 == '-h' ]]; then
       FILESIZE=`numfmt --to=iec $FILESIZE`
       FILESIZE="${(l:MAX_LEN[5]:)FILESIZE}"
     fi

numfmt - tool from coreutils

[chrstphrknwtn]

@sattellite numfmt is not generally available, not even with Xcode Command Line Utilities on Mac OS X, nor Build Essentials on Debain based Linux (as far as I know).

[sattellite]

@chrstphrknwtn strange. It was added in coreutils-8.21 (2013-02-14). numfmt in Debian was added in coreutils-8.21-1 (2013-07-21).
All Linux distributions have this tool.
I don't know anything about Mac OS X, sorry.
