Hello,

  when I execute 

(format-time-string "%h")

I get a return value of "" instead of "nov" meaning
November, the current date month. On the contrary,
execution of

(format-time-string "%b")

correctly returns "nov". I suppose this is
due to the runtime of my Windows installation
(an ordinary Windows 7 64-bit) not supporting
C99 format modifiers of the C function "strftime".

  My conjecture came after reading of this page:
http://www.cplusplus.com/reference/ctime/strftime/ .

  I kindly ask if someone good-willed Emacs user
might see if the problem happens on his/her
Windows machine. A test on Linux could be also
a useful counterexample.

  If it affects other users too, my suggestion is to
simply add a note in the docstring of format-time-string,
saying that modifier "%h" requires a C99-compliant
runtime. 

  Thanks for your attention, kindest regards.

  Andrea
