[Emacs-diffs] emacs-25 b1abce1: Restore leading space in movemail pop output

[Paul Eggert]

branch: emacs-25
commit b1abce1a30c66a22766e3d4b8b4ff9ae852f150c
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Restore leading space in movemail pop output
    
    * lib-src/movemail.c (movemail_strftime) [WINDOWSNT]: New function.
    (strftime) [WINDOWSNT]: New macro.
    (mbx_delimit_begin): Go back to previous version of this code,
    now that there’s a special-purpose WINDOWSNT implementation
    that should do the right thing.  That way, the output continues
    to use leading space rather than leading zero for day of month.
