Statifc buffer version of name_quote()

[metux]

name_quote(), which returns a newly allocated string, is used in many places where a static buffer (eg. on stack) would be fully sufficient.

And what size of that static buffer will be fully sufficient?

[metux]

PATH_MAX ?

1. What about potential buffer overflow in execute_menu_command() (src/user.c:654)? User's input parameter is not length-limited.

2. The static buffer is effective when you allocate and free some piece of memory very often, many (hundred or thousand) times per second. But name_quote() is called once in each place where it's called.
