[PATCH v3 1/2] git-p4: add test case for "Translation of file content failed" error

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

A P4 repository can get into a state where it contains a file with
type UTF-16 that does not contain a valid UTF-16 BOM. If git-p4
attempts to retrieve the file then the process crashes with a
"Translation of file content failed" error.
