Fix for Issue #1961 (reviewed by Josu)
 * Remove instances of "Specifies the..."
 * Remove instances of "Indicates that..."
 * Reword instances of "Specifies to..." (which doesn't really make
   sense anyway)
 * Change instances of "This utility may be used..." to "This utility
   can be used..." as discussed in a previous issue
 * Change some erroneous instances of "may" to "might" or "can". This
   might sound like a pointless change but it has implications for
   localization - "may" is generally ambiguous.
