[Sshpass-devel] Option for reading from arbitrary environment variable

Hi,

There have been some situations where I've needed to invoke sshpass a
couple of times in a particular environment. The -f option reasonably
allows you to read from an arbitrary file, rather than saying "this will
always read from the file ~/.sshpass": I felt the same advantage could be
derived from an option to allow you to read from an arbitary environment
variable rather than one with a fixed name.

There is a patch on sourceforge implementing this as a -E option:
https://sourceforge.net/p/sshpass/patches/14/

I am not really familiar with sourceforge, svn, C, or roff, so I'm happy to
receive feedback.

Thanks
Chris
