New description:

 The pretty_print function currently takes only one argument. This somehow
 makes it difficult to print multiple things in one line, for instance the
 following is currently not possible:
 {{{
 A = identity_matrix(2); pretty_print("A = ", A)
 }}}
 with the output being "A = <the matrix A on the same line>"

 I am attaching a patch which allows pretty_print to take in multiple
 arguments. It is based on some code by _leif @ #sagemath (See
 http://sagenb.org/home/pub/3111/ ). Also kini @ #sagemath helped in
 passing the doctests.

 The modifications are to 1) the function pretty_print 2) the doctests in
 pretty_print 3) the doctest in pretty_print_default (whitespace issues)

 -----

 Apply only [attachment:trac_11775-pretty_print_multiple_args.4.patch] to
 `SAGE_ROOT/devel/sage`.

Comment(by ppurka):

 Updated documentation to be more consistent with the existing format.
