[PATCH] kbuild: make 'cscope -q' play well with cscope.el
I tried the Linux Makefile 'make cscope' target, and found that the generated database is not compatible with 'cscope.el' under XEmacs. The thing is that 'cscope.el' does not allow setting the command line options to the 'cscope' commands it runs, and it errors with a message about the options not matching the ones used to generate the index. It turns out the cscope designers already thought of this. The options can be written into the "cscope.files". The included patch moves the "-q" and "-k" options from the 'cmd_cscope' to the 'cmd_cscope-file', echoing them into the top of the files listing. Now the index is generated with the "-q" option, and when 'cscope.el' performs it's search, it uses that argument as well. Lookups are fast and everyone is happy.
