ffmpeg 2.7 ignores forced FourCC (-vtag) while multiplexing to AVI

Description
Summary of the bug:
Multiplexing a raw MPEG4-ASP stream created by xvid_encraw (*.m4v) into an AVI container does not use the FourCC enforced with the parameter -vtag (instead keeps "FMP4").
How to reproduce:
ffmpeg -y -i "*.m4v" -vcodec copy -vtag XVID "*.avi"
More details in the attached report output.
Despite reporting to use the enforced FourCC "XVID", the AVI still contains the FourCC "FMP4" (for both locations in the AVI header).
