commit 79dbe4ed05fd29c1da7cc0af406dfdf306738553

    Book: corrected two minor typos in newly added example
    
    Until now, the example in the book for cropping multiple HDUs of a FITS
    file had two typos: the 'hdu' variable was read as '$$hdu' and there was no
    '--width'. Both would cause a crash.
    
    With this commit, a single '$' has been used for the 'hdu' variable and a
    width has been added.
