search bug in *cscope* buffer with multiple cscope databases about xcscope.el

[dkogan]

Hi. Thank you for the report, and I apologize for taking so long. I fixed this in

https://github.com/dkogan/xcscope.el/commit/efa27e22798671356f6cb7a647afb40be326b7ac

The fixed code reads the current directory from the point location in the cscope buffer. I don't use the cscope-database-regexps, so I don't yet have a sense if this is a good default. In your example, searching for "a" in the "a.c" cscope result would do what you want, looking at all the directories in cscope-database-regexps. But searching for something in the "b.c" cscope result would use the database in bdir/ and thus would not touch cscope-database-regexps. Would it make more sense to remember that that whole search came from the regexps entry in dira/ and for subsequent searches to all do that too?

I verified that https://github.com/dkogan/xcscope.el/commit/efa27e22798671356f6cb7a647afb40be326b7ac works for the example. I think the current behavior is good enough.

Thanks for fixing it.
