added emacs binding to "Find assignments to this symbol"

This is CVS revision 1.15
Added optional autoclose.  Also fixed [Ret] key for plain Emacs.

This is CVS revision 1.16
fuzzy matching now works as intended

The cscope-adjust variable indicates whether the line number reported by cscope
should be the target of xcscope.el navigation operations, or whether a search
should be done around that line. Prior to this patch, this variable was
effectively always on, causing fuzzy searches even when they weren't desired
updated header comment block

Updated the contact info, removed bogus versioning, date information
updated process-control calls to make this work over TRAMP
filled incomplete comment
cscope indexing status is now reported in the echo area

Previously this popped up a plain buffer. The echo area is by definition
transient, so it goes away by itself and the user's workspace isn't disrupted

added missing comment about the new find-assignments functionality
'q' buries the *cscope* buffer AND stops displaying it
minor indentation fix
comments
*cscope* buffer no longer cleared between searches: results are accumulated

The history can thus be observed. Added user-customizable variable
cscope-max-cscope-buffer-size to prevent this buffer from growing unbounded
fuzzy matching now works together with the history-rich *cscope* buffer

Previously fuzzy matching worked off of the global cscope-symbol variable. This
variable contained the string to search for. Since the *cscope* buffer now
contains many consecutive searches, there must now be multiple values of
cscope-symbol for different parts of the buffer. This is now implemented with a
text property
added menu entry for cscope-close-window-after-select
added history-navigation commands
cscope entries can now be activated even at the end of a line in *cscope*

previously the text properties that contained navigation information were
missing from the trailing newline on each line. The newline now contains those
properties as well
The *cscope* buffer is no longer read-only, and undo is enabled
*cscope* buffer now works a bit like a diff-mode buffer

One can now navigate through results in a search with M-N,M-P and kill a result
with M-K.

In a later patch one will be able to now navigate through FILES in a search with
M-n,M-p and kill a file with M-k.

This is like files and hunks in a diff respectively. The 'v' and 'V' bindings
have been removed for consistency. These bindings all work from within a
*cscope* buffer only. There is NO corresponding C-c s ... binding
I never suppress empty matches; always report when no matches were found
The mouse face respects cscope-use-face
