Subject: file: try ismp4() before ismp3()
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=80fdafd1d6bc27d7a94fabc12f4af37285a17338;p=plan9front.git

file: try ismp4() before ismp3()

It is possible to find the mp3 sync word near the start of an mp4
file.  As such, file(1) could incorrectly identify some mp4s as mp3s.
