Denton Liu ad6dad0996 *.[ch]: manually align parameter lists
In previous patches, extern was mechanically removed from function
declarations without care to formatting, causing parameter lists to be
misaligned. Manually format changed sections such that the parameter
lists should be realigned.

Viewing this patch with 'git diff -w' should produce no output.

/* Help to copy the thing properly quoted for the shell safety.
* any single quote is replaced with '\'', any exclamation point
* is replaced with '\!', and the whole thing is enclosed in a

*
* For example, if you are passing the result to system() as an
* argument:
*
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
*
* would be appropriate. If the system() is going to call ssh to
* run the command on the other side:
*
* 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.
