Hi Olly,

This patch doesn't seem to be working for me.  The substitutions appear to fail
when anything is quoted or grouped.

$ ./omega 'P=author:foo'
Xapian::Query(Afoo:(pos=1))

$ ./omega 'P=author:(foo)'
Xapian::Query((author:(pos=1) OR foo:(pos=2)))

$ ./omega 'P=author:"foo"'
Xapian::Query((author:(pos=1) OR foo:(pos=2)))

$ ./omega 'P=author:"foo"' 'P=title:"mike"'
Xapian::Query((author:(pos=1) OR foo:(pos=2) OR titl:(pos=3) OR mike:(pos=4)))
