>Description:
Install(1) deletes the source file unless -c is specified. This sets us
against FreeBSD, OpenBSD, every version of Linux, and all SysV derived
systems. 

I raised this on tech-userlevel: the consensus seemed to be that
our behaviour was not very useful, and should be fixed to make us
compatible.
>How-To-Repeat:
$ touch testfile
$ install testfile otherfile
$ ls testfile
