Following the list discussion, define two functions, quote_c_style and
unquote_c_style, to help adopting the proposed way for quoting funny
pathname letters for GNU patch. The rule is described in:
http://marc.theaimsgroup.com/?l=git&m=112927316408690&w=2
Currently we do not support the leading '!', but we probably should
barf upon seeing it. Rule B4. is interpreted to require always 3
octal digits in \XYZ notation.

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