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
mailboxes), the access token used for the LOGIN command may not fit
into the currently used buffer of 1000 characters. In my case, I need
the buffer to be at least 2000 characters long. To make this more
future-proof, I increase the buffer size to 4000 characters.
