This patch introduces two changes:
1) Temporarily disable fuzzy matching for searches
to which it does not apply, such as when searching
functions called by a function.
2) Added functions and keybindings that control the
displaying of the *cscope* buffer.
The first change (1)) fixes a change that was
introduced by by revision 1.6 of xcscope.el. Without
it the cursor may be incorrectly adjusted to match what
was searched for instead of what was found.
The second change (2)) only saves a few keystrokes and
mouseclicks by making it easier to control when the
*cscope* buffer is displayed.
