We can not assume "'path' + 'ctx->fs_root'" must be less than MAX_PATH,
so need use snprintf() instead of sprintf().
And also recommend to use ARRAY_SIZE instead of hard code macro for an

- fix sprintf() bug, can use snprintf() to fix it just like other
places have done -- apply this patch (comments need be improved).
- improve 9pfs features -- support 'unlimited' path internally.
before do it, better to get original authors' response firstly.
I guess, we need change quite a few areas and have a full test.
Thanks.

In "vl.c", at least, we can simplify the code below, so can let readers
read professional C code (especially for new readers, which often start
reading code at main function).

- Eliminate a superfluous local variable in main().

after that, I think we can do somethings to help you to achieve your ideas.
