Subject: [PATCH] Increase imap_vprintf buffer size

This fixes "Fatal: buffer too small. Please report a bug." error. See

+
https://sourceforge.net/p/isync/mailman/isync-devel/thread/87fsevvebj.fsf%40steelpick.2x.cz/#msg37731590

for related discussion.

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.
