Hello, 
for the use with xargs -0, gnu find has a -print0 option allowing the user to process files even having the <LF> character in their name. however, in one wants to make à check on the content, this doesn't work anymore : One can write find <DIR> <CONDITIONS> -print0 | xargs -0 grep -l <REGEXP> | tr '\n' '\0' | xargs -0 ...to have de second xargs allows files with <SP> or other special characters in their names, but this won't work with files with <LF> in their name.
For this reason, I suggest we add a gnu --print0 option to grep (to be used with -l) which will separate the filenames produced with grep -l, with <NULL> characters instead of <LF> characters, in order to allow the correct processing of files with a <LF> in their names.

One might object that making a file with an <LF> character in it's name is stupid, but it is always possible to create one by mistake, juste with a wrong quote matching in shell commands or scripts.
Best regards, 
Camion
