   4 Subject: [PATCH] Increase imap_vprintf buffer size
   5
   6 This fixes "Fatal: buffer too small. Please report a bug." error. See
   7 https://sourceforge.net/p/isync/mailman/isync-devel/thread/87fsevvebj.fsf%40steelpick.2x.cz/#msg37731590

  10 When using mbsync with XOAUTH2 authentication (needed for Office365
  11 mailboxes), the access token used for the LOGIN command may not fit
  12 into the currently used buffer of 1000 characters. In my case, I need
  13 the buffer to be at least 2000 characters long. To make this more
  14 future-proof, I increase the buffer size to 4000 characters.
