" par options
"
" e[expel]
"
" If expel is 1, superfluous lines are withheld from the output .
" Defaults to 0 .
"
" g[guess]
"
" If guess is 1, then when par is choosing line breaks, whenever
" it encounters a curious word followed by a capitalized word, it
" takes one of two special actions. If the two words are separated
" by a single space in the input, they will be merged into one
" word with an embedded non-breaking space. If the two words are
" separated by more than one space, or by a line break, par will
" insure that they are separated by two spaces, or by a line
" break, in the output. Defaults to 0.
"
" q[quote]
"
" If quote is 1, then before each segment is scanned for bodiless
" lines, par supplies vacant lines between different quotation
" nesting levels as follows: For each pair of adjacent lines in
" the segment, (scanned from the top down) which have different
" quoteprefixes, one of two actions is taken. If invis is 0, and
" either line consists entirely of quote characters and spaces
" (or is empty), that line is truncated to the longest common
" prefix of the two lines (both are truncated if both qualify).
" Otherwise, a line consisting of the longest common prefix of
" the two lines is inserted between them. quote also affects the
" default value of prefix. Defaults to 0. (See also the p and i
" options.)
