gud-print

[Nick Roberts <nickrob@snap.net.nz>]

Currently gud-find-expr-function computes the expression at point:

m[4] = 2;
i22 = m[4] + 7;
      ^

If the cursor is at m it prints m[4]:

$1 = 2

Below is a patch for gud-print which allows the user to select a region.
For example, selecting "m[4] + 7" gives:

$2 = 9

I've tested it with transient-mark-mode on and off and it seems to work in
both cases.

Is it completely general?
