#88 quick search for selected function

[mikhail nefedov]

Sometimes it is useful to quickly search for the function of the selected line in the selection. Please consider the patch. Pressing '&' during selecting cases cscope to search for the selected function without other means of cutting/pasting/re-typing.

I can vaguely see some merit in the feature itself, but I can't help hating the way you implemented it. Why did you have to trample all over an existing function to make it do something so unrelated to its original job, causing senseless changes all across the program?

I made a change to make this thing work. I am not saying this is the best change. I don't know enough of the code to come up with the best possible way. Please suggest a better fix.
