Since earlier commits removed the inclusion of cache.h from mailmap.c and quote.c, it feels odd to have the extern declarations of global variables in cache.h rather than the actual header included by the source file. Move these global variable extern declarations from cache.h to mailmap.c and quote.c.

|
|
* single quote pair.
|
|
*
|
|
* For example, if you are passing the result to system() as an
|
|
* argument:
|
|
*
|
|
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))

|
*
|
|
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));

* sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd));

|
|
* Note that the above examples leak memory! Remember to free result from
|
|
* sq_quote() in a real application.
|
|
*
|
|
* sq_quote_buf() writes to an existing buffer of specified size; it
|
|
* will return the number of characters that would have been written
|
|
* excluding the final null regardless of the buffer size.
|
|
*
|
|
* sq_quotef() quotes the entire formatted string as a single result.
