# HG changeset patch

# Node ID 194a18b7e904c83c8ef3ba6a0a7d262beff1ae7c

status: added option -p and -0 to assist xargs

The -p option strips the status prefix of each file, while
-0 ends each file with a NUL character, instead of a newline.
Together, selected group of files can be passed to 'xargs -0'
for further processing.
